All three bras work the same. Which bra you choose depends mainly on the neckline of the outfits you typically wear, since the bra bar is designed to follow the shape of your top or dress’ neckline.
SHALLOW PLUNGE: If you wear tight dresses, crop tops or shallow plunging necklines, you’ll want to purchase the “Shallow Plunge”. The Shallow is designed to replace a standard Strapless bra. This is the most popular of our three bras. Any outfit you would normally wear your “old-school” strapless bra with you can now wear the Shallow, with the added bonus of it also being fully frontless and backless. It's also our best bra for tight fitting clothing, since the higher, shallow plunging sits below/beneath the curve of your breasts.
MODERATE PLUNGE: If you wear necklines that plunge mid-torso, this is the bra for you. The Moderate Plunge also provides the most lift and cleavage. If you have any doubt whether to choose the Moderate or the Deep Plunge, the Shallow or Moderate is usually the best bet.
DEEP PLUNGE: This bra is designed for extreme, daring, think-J-Lo on the red carpet type dresses, which plunge down to (or past) the belly button. The Deep Plunge is recommended for experienced Misses Kisses customers or for women who are confident their outfit's neckline will plunge this low. But be aware -- you cannot wear the Deep Plunge with a mid or shallow plunging neckline or the bra bar WILL show through your clothing.
