Small band + big cup DREAM!

I’ve found it so difficult to find a bra that fits me well as a 32DDD-G. This it it!! A lot of the other popular brands I’ve tried have such a wide center that my breasts sit too far apart. I love how this bra sits on me and how the cups don’t make my breasts look even bigger or a weird shape! I’m also only 26 years old and the fact that this bra comes in my size and doesn’t make me look like an old lady is a dream. It’s so comfortable too. No digging in in random places and the straps hold me up without hurting my shoulders. This is the one!!

So sheer

I know it’s marketed as sheer but I wasn’t expecting it to show literally everything. I had to return this one.
