A Demi Bra
What it does: Consider this the ultimate date-night bra. This ultraflattering underwire option, which comes with or without padding and is often made with lace elements, has cups that are angled to expose the top of the breast.
When to wear it: It's perfect for low-cut tops or those with wide scoop or square necklines where an everyday bra would show. And, if there's ever a chance your bra will be seen by a lucky partner, this is the style that is a true crowd-pleaser.
When to replace it: You won't wear it more than once a week, but because it is more delicate, this bra should still be replaced every year to 18 months if it's starting to lose its hold.
