Hi , me again , a quick tip on binders:

Do not compress using an ace bandage , as you have mentioned not healthy to compress to much.

Tip 1 : One size down with a sports bra might help . > link

Tip 2 : Corset Liner , when worn in the upper chest area it will compress slightly more that a sports bra so DO NOT size down ! >link
