So i bought a bunch of cute tops at Forever 21 and they have racerback backs. I'd always seen these things in the 'forbidden isle' at walmart lol... and thought hey what the heck? I actually bought mine from Bed, Bath, and Beyond for five bucks (they are on sale now). They are great!!!! I put them on about 2 hours ago, and it wasn't until I was typing this review, that I remembered...I still have the strap perfect on! Its comfortable for me, i don't feel it at all. Granted, I am small in frame and am able to wear bras from non-department/specialty stores, so i don't have any bulky-ness, etc. that other larger cup women may be experiencing from these. Great buy...glad they were on sale and they work :)
