Closer to 4 than 5, just because it does roll up a little. It's annoying but doesn't seem to be too noticeable, especially with more loose t-shirts.
I really, really liked it. I'm quite short, so my underworks full length binder was kind of annoying because it felt so long. In contrast this length was great, and the material was softer and more comfortable. Like I said, it does roll up, but it hasn't been a huge problem for me so far. I did order a size smaller than underworks as suggested and it fit really well, even if initially getting into it was a little snug. I highly recommend this binder and will be buying another one!
This is the MOST comfortable binding I’ve ever worn, just from the material and fit. If you’re using underworks sizing, though, I’d recommend going down a size from what you measure because this one is pretty loose.
This binder is incredibly comfortable, though I ordered based on measurements taken for Underworks brand (which work amazing but cut into my underarm/sides). This binder is not as tight/flattening. Will try a size smaller.
