Chest size at time of use: 12C (Australian measurements) – around 32.5 inches I think.
Comfort: 3/5
  • This is my first binder, so I have nothing but cotton sports bras to compare it to, but I’m not finding it very comfortable. When I first put it on it made my back ache and my breathing felt constricted, these both passed within a half-hour or so, and I expect were factors of being unused to wearing something this tight. The top stops at the base of my ribs, so doesn’t compress my stomach at all, which is good. My big problem is that some of my chest tissue has been pushed out of the arm-holes and I can’t seem to adjust myself in any way to stop this happening. This looks like under-arm fat, which isn’t nice, and the arm-holes themselves are digging quite uncomfortably into these rolls of tissue, bringing overall comfort down. I won’t be able to wear this every day, and I don’t think I’ll be able to wear it while doing anything very active, it cuts in too much. According to the measurements on the Underworks website I have the right size for me, so I think it’s just a factor of the design versus my chest.
Effectiveness: 5/5
  • I don’t know how it will bear out over time, but brand new this is the flattest I’ve ever been since before puberty. Brilliant.
Discreetness: 4/5
  • Under dark and/or loose-fitting shirts you can’t tell I’m wearing anything at all. In v-necks or open-necked button-downs the little bit that shows just looks like I’m wearing a tank or undershirt underneath. Under white/translucent shirts however, it can easily be seen, and it’s obvious that it only covers my chest. I don’t wear tight shirts, so the shape of it showing under tight shirts is not a problem for me.
Overall : 3.5/5
  • This was really, really difficult to get on. I got a small, which was the correct size for me according to the sizing on the website, and once on it fits fine, but I had a LOT of difficulty getting it on over my shoulders. It was awkward and kept bunching painfully around my upper arms and getting stuck. I eventually managed to get it on without actually straining my shoulder, but I very nearly gave up. Definitely something to have a helper on hand for if you can, and not good for anyone who is prone to dislocating their shoulders or needs to get dressed quickly.
    It’s great for flattening my chest, but being so hard to get on (and I assume off, I haven’t tried that yet), and the way it cuts around my arms really brings the rating down IMO. I can’t wear this every day, I’ll keep it for the days when my need to be as flat as possible is stronger than my need to be physically comfortable.

Product name: V-Neck Mid Length Binder
Manufacturer’s website:
Price: $29.00 + shipping and handling
Cup & band size & chest measurements in inches at time of use: 40C or 42 chest

Comfort: 5/5

  • Very comfortable, can go the whole day with it and completely forget I was binding. The bottom of the binder doesn’t dig in my sides or armpit. It’s like wearing a high compression bra. It has Velcro fasteners so putting it on is easier the over-the-head binders. I can eat as much as I want and there is no pressure on my stomach.

Effectiveness: 5/5

  • I could never be flatter. No lumps, seamless binding effect.

Discreetness: 5/5

  • You will never notice. I wear v-necks the majority of the time and you would just believe I was wearing an undershirt.

Overall : 5/5

  • Product is incredible and never been happier. Easy to put on, comfortable, Binds incredibly flat with zero lumps, and unnoticeable. And I wear a normal compression shirt not because I want to be flatter its just because I have curves that like to come out over binders when no one asked for it. Which is good advice for the bigger guys. Before and After pics down below

Cup size at time of use: 34 C

Comfort: 4.5/5

  • It’s made of lycra and cotton, which means it’s soft– it feels a lot like a snug sports bra. There was a little bit of abdominal pressure, especially after eating, though it resulted in minor discomfort at worst.

Effectiveness: 5/5

  • There were small lumps left, but they didn’t look out of place. While I’d have loved it if I ended up flatter, there was no more give left to my chest– it’s about as good as I’m going to get without surgery.

Discreetness: 4.5/5

  • Remember how I said it’s made of cotton and lycra? The result is that it actually looks like a cotton tank top or undershirt. It’s a little bulky, but even that seems to come from the double-sided design more than anything else– it’s reversible, light blue on one side and white one the other– and will not look out of place even when it is highly visible.

Overall : 4.5/5

  • Seriously, I love this thing. All that’s left is to see how durable it is, but I have high hopes.
  • This binder is NOT currently available in sizes smaller than Medium.

  • The under-stitching has a tendency to rub kind of hard, but overall its a very nice feeling. Wouldn’t recommend sleeping in it.

Effectiveness: 5/5

  • I am completely flat chested with this shirt on.

Discreetness: 4/5

  • I wouldn’t wear it with v-necks since the fabric doesn’t exactly feel like cotton, since it is spandex. Otherwise you cannot tell you have a compression vest on, looks like a regular t shit.

Overall: 4.5/5

  • I say [four and a] half because the price for one single item is pretty high, but then again having my dignity and self image restored to normal is priceless. This shirt works for extreme gynecomastia.

  • I like it that it’s not racer back (like most sports bra). From under my clothes, it looks like a singlet, which is great! Cos I hate it when people could see that I am wearing a sports bra.

Overall: 4.5/5

  • All my life, I have been looking for an effective and comfortable binder. I was sixteen then and I have only tried binding with bandages (I’m not kidding…) the old school way ONCE. It was effective and very convincing… but i could hardly breathe. After so many years I didn’t dare to try it again. I resorted to wearing sports bra (one size smaller than I should) to flatten my chest. It did reduce my CUP C chest to a CUP B I think.
    And then this year, after more than ten years of wearing sports bra (which didn’t keep me very happy… I still had to wear big and thicker clothes to hide my chest…), I finally found the best binder ever! It works! Reduces my CUP C chest to look like a CUP A! Although my chest is not completely flat like a man’s, it was very comfortable! And i’m so glad that i chanced upon this binder review blog! Hey great job! Keep up the good work! It’s really something good for the community ya… =) Because I really think that binding too tightly could be… erm… maybe a little bad for health? So I’m happy to share that achieving the appearance that we want could be attainable with a little compromise too! =) At least… I think my chest looks flat enough to be convincing! And i feel very confident now! heh!
    I just wished that they could have more designs and colours soon! Oh and i did had some trouble wearing it and pulling it over… but now I’m an expert!

Product Name: T-Kingdom M1700

Manufacturer’s website:

Cup size at time of use: C?

Comfort: 3

  • Comfortable when I first put it on in the morning, but starts to dig in to underarms and leaves painful red indents that sting even after I took it off. The velcro was very itchy if not lined up just right. It would be ok to wear once in a while, but certainly not comfortable enough to wear daily.

Effectiveness: 2

  • It didn’t do much by itself, I had to wear 2 sports bras underneath for it to do much. It didn’t get me flat, but since im pretty big to begin with, it looked natural.

Discreetness: 2

  • The chest material is different than the rest, so theres no way it could pass as an undershirt. Also, it sticks out a little at the top. I also had to adjust it fairly often.

Overall: 3

  • Not the most comfortable thing i’ve ever worn, but I could pass well enough.
