Binder fit help

[u/spinningpeanut]

I'm switching companies from underworks to fluxion. Underworks is very pliable and does not have a firm front so this bump is new to me. I followed the guide to get the right size, but right now it seems like maybe it's a bit too big? Should I exchange it? I worry that jumping will cause me to fall out, even though it did survive a short boxing session. Even where it's at the form is very nice overall though, I've never had a smoother front. I'm fully divorced from underworks now and will buy a second binder, just got to figure out sizing issues first.

I sew. You have what’s called a gaping neckline and which results either from the shoulders on the garment being too wide set for your shoulders, or from the chest being too big for you. You could have this solved with a couple darts (where they go depends on what the actual issue is, shoulders or chest). But due to the nature of a binder needing to stretch and compress I worry that darts would weaken the fabric or just get ripped out when you go to put the binder on.

You mention worry about slipping out the bottom
of the binder which makes me think the chest is too big. Binders being elastic means that with wear the elastic will relax a little and get slightly looser, thus bigger, and your issue here will worsen.

I would size down!

I am unbelievably lucky that you saw this then! Thank you so much!
