Not over a shirt. Not over a binder or other garment.
STEP 1:
Wrap the tape measure all around your chest and back right under your armpits. Above the bust.
If done correctly with the chest puffed out this should give you enough room to take a full breath. Please do not wear a binder you can't take a full breath in.
STEP 2:
Measure around the widest point of bust, this might be around nipples for many.
STEP 3:
Measure around the under bust.
STEP 4:
Take average. Add measurement from step 1 + measurement from step 2 + measurement from step 3. Then divide that by 3.
Example:
Step 1 = 38, Step 2= 42, Step 3= 37
38+42+37=117
117/3=39
39 is the chest measurement
According to the size chart an 2XL fits 38-40 chest so 2XL should be an ok fit.

Binder Sizing Help
Tools needed:
You will need something to measure with. A soft measuring tape is recommended.
What if I don't have a soft measuring tape?
If you don't have a soft measuring tape you can still measure using a string, cord, belt, or anything you can safely wrap around your chest. Wrap it around yourself and then measure the length using a ruler, yardstick, or another measuring tool.
If you do not have a ruler, you can use an object with a known length like an uncased phone to estimate. For example, I have an iPhone 12. Apple lists the length as 5.78 inches without a case.
I tested this myself using a laptop power cord. I wrapped it around my chest just under my armpits for step 1, inhaled fully for breathing room, and pinched the spot where the ends met. Then I measured the cord using my phone. It was slightly less than 7 phone lengths long
7 times 5.78 equals 40.46 inches. Since it was just under 7, I rounded down to 40 as my upper chest measurement.
Factor in the fit of other brands:
What sizes have you tried in the other brands? Compare their size chart to ours.
Remember: All bodies are unique!
You really have to try binders on. Measuring properly should get you close to your size. People with the same measurements can have different fitting outcomes because we are all unique. We all have different shapes and densities of our bodies.
What if the size I order doesn't fit?
You can return it. If your purchased the binder on sale we can honor the sale price when your order another size to try. We will honor the sale price even if the sale you ordered during has ended. Just ask us before your order.

Im very impressed by the quality. Reasonable shipping time. Genuinely feels comfortable to wear and has amazing results, the flattest Ive ever been wearing a binder. Its been hot as anything outside and humid to boot, the mesh backing feels like a savior while working on cars 10 hours a day. Will be reccommending to my friends who are looking for new binders.

absolutely amazing as always. Ive been using this brand for a long time now because its the only one that doesnt hurt my ribs after a while. I previously had a 2XL but needed a smaller size bc ive lost a lot of weight and this one is just perfect
This is probably the most comfortable binder I have ever put on my body. For real, it's the first one I've ever worn that LEGIT I don't feel like I'm wearing something with compression. I don't know what magic they are using, but I'm so glad I bought this. I am a 38DDD usually, bought the 3XL, and legit, it looks great! (Keep in mind that at my size, nothing is ever going to FULLY flatten- this demonstrates a SIGNIFICANT change of shape.)
When I received this binder yesterday (for me, the 17th of August) , I was ecstatic. I never had a binder of this quality before (I bought cheap ones trying to cut corners but those were obviously not good), it is comfortable and it flattens very well. This was my first time shopping here and I heard of you guys from social media and purchased out of curiosity since it is very hard finding binders for larger chests that are very noticeable. Also, it shipped very quickly within maybe 2 to 3 days after purchase. Five stars 🌟 🌟 🌟 🌟 🌟, you made me a very happy guy ❤️.
Quite good compression but the fit is strange (it is hard to get on/off without ripping noises, which I suppose are seams tearing, and additionally there is a lot of loose fabric at the bottom in the front). Such is untailored clothing, I suppose
Gave me (32G UK size) the flattest chest out of all of the binders I've tried, and it's very comfortable. It feels about as constrictive as a rather tight sports bra (you still need to practise proper binder safety!) and it's easy to breath deeply in. Plus, the mesh backing makes it look like a normal sports bra, so it's useful if you need to stealth.
Had this binder for about 2 years now, worn almost daily, and it's held up excellently. Binds very well and is incredibly comfortable, even when it's very hot in Summer the back helps it to not get too sweaty. I've had trouble with binders in the past gaping a bit near the armpits but this one is only just starting to after 2 years of use (and probably not the best care) so it's been great.
This is the first ever binder I ever purchased, I was a little worried I might’ve measured myself wrong, but the binder that arrived was great, it’s very light and breathable especially with the mesh. It doesn’t make me feel hotter and it isn’t very tight. My chest was definitely flatter, which I was happier about!
I’m usually about a b/c cup so this took off a lot! When I did measurements I got about 36.6 so I got an xL but it’s slightly big around the bottom so I’ll probably buy a smaller size to see if that binds better. Overall quite comfortable and works great but if you’re on the cusp of two sizes like me maybe go smaller!
I was worried about discomfort, but the bind is super comfortable and I get no soreness after hours of wear. Binds super well, and I didn't realize how much better it'd make me feel! Definitely recommend. :)
This is my first binder so i can only compare it to a sports bra but i really don’t have any complaints. I think i went into this experience with realistic expectations. I wasn’t expecting top surgery results (super super flat, bc obviously i still have boobs) I was expecting it to be much better than a sports bra and that’s exactly what i got. I haven’t worn a regular bra in a long time so i think my size was 34C or 36C. it’s much more comfortable and convenient for me instead of tape. The comfortability of this binder is great, it feels less noticeable than a sports bra which is surprising to me. I’m very happy with my purchase and i’m happy to support a trans owned brand! 🏳️⚧️🧡🤍🩷
The binder fits well and is incredibly comfortable, it flattens me out very nicely considering I have DD's
This is my first binder ever and has outdone my expectations by tenfold.
This is the most comfortable piece of clothing I own. It doesn’t hurt like my gc2b binder did, it doesn’t feel like it’s digging into my ribs, and it doesn’t make me sweat substantially more. It’s lightweight and breathable while still being an amazing binder. I forgot that I was even wearing it because it’s that comfortable. I love it so much and I’m so happy with it!
Sorry for bad camera quality but this is a great binder definitely my new favorite brand and one of the only ive found that properly fits us bigger guys!
For being my first binder, I think I made an excellent choice ordering from here :3 Extremely comfortable where I usually can’t tell I’m even wearing a binder and barely feels constricting (especially being someone who has asthma).
I highly recommend this! I’ve felt significantly more happier since getting it :) thank you so much 🫶
I'm a C36 cup and most binders I tried barely made a dent in compressing my chest, this binder has made me the flattest I've ever been and normally I have to wear 2 binders to even be semi close to these results! (Please don't double bind)
Not only is it the best binder for compression it's also the most comfortable, it doesn't crush my ribs or put too much pressure on my back like all of my other binders.
It's %100 worth the money to go ahead and get a better quality binder for best results and avoid spending the same amount of money buying multiple binders to try and fine the same results.
This was my first time buying a binder so at first I thought I had ordered a size too small, but by the second wear it was already so much more comfortable! I am absolutely in love with how it looks under my clothes, thank you so much :)
i came out as trans & started binding when the only brands you could really get safe binders from were gc2b and underworks... and let me tell you, even with how happy i was with my first ever binder at 13, it was NOTHING like this binder!!! the fabric is an amazing, non-intrusive texture. it's smooth, lightweight, and comfortable. nothing like those scratchy front panels on old gc2b binders and the elastic back that would start peeling like old rubber when it began to wear down. even just from the first few wears, i can tell that this binder is built to LAST!!!
not only that, but i am by no means a thin guy, and never have been. no binder has been able to really be worn well without eventually riding up too much and compressing the bottom of my ribcage a little too much. and while this binder DOES ride up a tad after a bit, it tends to stay in place much better and for much longer!!
i genuinely feel like i just look like a cis dude in a cropped compression top in this thing. genuinely 10/10 binder, holy shit.
I bought this for my boyfriend he said it is the most comfortable and breathable binder he has ever had we havent had it for very long but so far it is amazing
Amazing!!! This is by far the comfiest binder I've had in a while - AND it actually works. I'd especially like to mention that I've had NO NEED for readjustments during the day which is a life saver especially at work, while with past binders I've had to readjust pretty much any time I bent over haha. As someone with a larger chest, I am very impressed by this binder and I will definitely be purchasing from here again. Package also arrived as scheduled and in perfect condition!
As a amab nonbinary person who has been on hormones for a decade I love this binder it makes me feel happy and euphoric I will definitely be buying again in the future 10/10 would recommend
I loove this binder!! It's very comfortable, breathable, and binds very well! For reference: I am around a C to D cup and got a size S binder. This flattens my chest super well!
Overall, I really love this binder from the elastic band at the bottom to the breathable fabric in the back. It’s comfortable while keeping everything in place, and without putting strain on my ribs and back. However, I do think this 4X size is too big for me as I have pockets of room out the sides of my chest causing less of a flat look and feel. Additionally, the breathable material on the back of the binder measures higher up on my back than some of my t-shirts making the binder visible.
Super comfortable, even after hours of wear. I love the band at the bottom so the binder doesn’t roll up whenever I sit down. I haven’t had to awkwardly adjust in the middle of the day from having to pick something that fits my chest as well as my ribs/upper stomach.
Size L. I wear a small/medium in tops. Followed the size chart and it worked for me
So far I love this binder! It's super comfortable while still doing a really good job flattening my chest! First time I wore it was for about 5.5 hours and really at no point did I feel like it was restricting my breathing.
It WORKS WONDERS for someone with a bigger chest, by no means does it make it look like there is nothing there but it helps so much and im so confident in it
I've never had a binder that I couldn't feel when wearing it, but these are so comfortable and lightweight. It does exactly what it's supposed to do, and my chest looks naturally flat when I wear it. I feel like I should have gone down a size, but that's why I have ordered two sizes.
I was very excited for this, as this is my first time purchasing a non-borrowed and should-be well fitting binder. My only issue is it is too short. I am 5'2 with somewhere around a B cup I believe, and I have spent the past two days non-stop pulling it back down and readjusting, which puts a lot of strain in my shoulders. It also does not bind as well as I had hoped, but I suppose I can only get so much out of a comfortable and safe bind. I am unable to size down as well, as it's already tight-fitting around certain areas for me. Otherwise, the material is very nice in texture and relatively breathable. It is very clearly well made as well. All around a pretty decent binder if your proportions are not as odd as mine.
The binder is extremely comfortable and binds really well! Ive not found a plus sized option that's affordable and has that front panel! Customer service was great and super communicative! It was well worth the wait for the restock! Thank you so much!
Best part is I get to support a trans owned and made business!! Beat purchase yet ❤️🏳️⚧️
Absolutely wonderful binder!!! Its fantastic! I thought it was gonna be too big! But it fits perfectly and doesn’t ride up! Doesn’t compress my ribs like my old binder! Easy to take on and off! Thr band can be a bit iffy sometimes with my stomach but other than that! Gets me flat like my old gc2b without the pain!
