How to fix your that is curling out!

So going to try this! I just got a brand new bra and today is the first time wearing it. I noticed (after I tore the tags off) that one of the cups was curling out. UGH! Most annoying thing ever!

I found this link and I am going to give it a try! Hope it works! I will tell my ending results and how well it worked for me.

Wish me luck!
