I wear a bra 24/7. My boobs are just too big. Lol I dont want saggy boobs. But if you have comfortable bras with good support there is no reason for them to hurt you. I read that 80% of women buy and wear the wrong size bra. You could go get measured so you know EXACTLY what size you need??
I can't wear a bra at night it kills me it hurts too bad lol.
