Reposhing this item I purchased from @katievillareal. Loved it, great compression support for my post surgery. Sizing reference is great for 300 cc implant and while you have swelling right after surgery. It got loose for me 4 weeks/6weeks in my swelling subsided. Maybe it would great for 350cc /400cc still be great compressions for 3 month post-op. Questions? Leave a comment below!
