I'm ok as long as I'm not shopping with my mom. When I pick out a cute bra or panties she's like "Ooh!!" and gets some but always ends up taking them back a few days later. She's got really big titties which is great but they don't have her size in that section.
I was never awkward about it but always had to force myself not to laugh when I saw a couple there. Everyone in that department are all doing the same thing and aren't remotely interested in you, teenagers world over think people are always staring at them (trust me, they're not). And anyway, bras aren't anything to be ashamed of
second time I went bra shopping. I was looking at bras and I was kinda tence (really tence). Then this lady came around the corner and I literally jumped. She gave me wired look and just kept walking XD. Anyways my point is it's only a big deal if you make it a big deal, so if you just look at bras like it's no big deal, then it's no big deal. If you jump evre time you hear something and keep looking behind your back then it's a bit of a different story.
