I ordered this support because of poor posture. I try and wear this daily and am seeing an improvement. My shoulders are pulled back and the saying " put your shoulders in your back pockets" is becoming easier. I recommend this to anyone experiencing the slumpy look or anyone with back pain, especially females with heavier breasts.
The order came quickly to Brazil, within a month the biggest. The top itself is odorless, the material is something similar to what the bras do. Personally, I did not feel any tension in the back area, but in general it can be worn as an accessory of clothes.
Comfortable, immediately corrects posture, makes it difficult to revert to bad posture. I wore it half the day my first day and I wasn’t painful or uncomfortable. I realized how untrained I’ve become as I kept catching myself try to slouch.
