Seriously?? Who the hell is going to wear this? A) It's a sweater, but it's sure as hell not warm and B) It's indecent. With a tank top it'd be fine (though still not warm) but with just a bra?
Sweater-corset? WTF! That's sure as hell not going to keep you warm, so why would you want a sweater? Besides being impractical, it's fricking ugly. The style of top, fine, but a different material is clearly called for.
Masquerading as a normal person day after day is exhausting.
