With a bust size of around 77 cm and a shoulder width of 40 cm the size chart calculator recommended an XS for me, I got an S instead as I prefer comfort over binding being autistic. It fits snugly, I don’t think an XS would’ve fit me, so I’m happy I chose to size up and recommend anyone else do the same, especially if your in between sizes. For my next binder I might get a size M for extra comfort. The binding itself is amazing, it got me almost completely flat which gave me a lot of gender euphoria, one thing I’ll say is that my breathing is a little restricted when wearing it, whilst cycling it was a bit of a bother but if you’re not planning on doing any moderate activity it is perfectly fine (mind you, this might also be because the size S is pretty tight on me, if you do plan on exercising in a binder please go a size up or use trans tape). Sensory issue-wise this binder was pretty good. The fabric is soft and doesn’t really irritate the chest, the only thing that I noticed was the band which dug a little into my stomach and the small-ish arm holes but it wasn’t a dealbreaker for me. This is definitely my favourite binder currently. Also, the zipper is a blessing in the morning when I’m groggy, was fighting for my life with other binders to get them on and off. It also means that whenever I need to take a quick break it is really easy to do so, which gives me both peace of mind and prevents me from getting overwhelmed when my neurodivergent mind decides I need it off immediately.
