I have a variety of bras. I have some VS Cotton for everyday, comfort wear. I have a couple of fancier VS push-up type bras too
I bought this bra in the demi to fit under my wedding dress. Despite being more padded than many of my other bras, it's super-comfy, and has less spillage than many other demis I've tried:
Incredible by Victoria?s Secret?:omg Incredible Bra, Incredible Videos & More
My other favorite lined bra is this one,
Body by Victoria Full Coverage. I love it because it is made with this Memory Fit lining that self-adjusts to fit your boobs better over time. I also have their lighter "unlined" bra--it still has a bit of lining, but not as much as the regular one.
So, I guess you could say I wear the bra that suits the occasion. If I want to look smooth under a tight sweater or a tight t-shirt, I go for the Body by Victoria lined or unlined, depending on if I need nude or black (the lined is nude, the unlined is black). If I need amazing cleavage, I go for the Incredible or the Body by Victoria bras. If I'm just wearing a regular t-shirt or going to sleep, I go for my VS cotton bras.
