Demi bras have cutaway cups or half cups that expose the upper part of the breasts. Also, the shoulder straps are typically set farther apart. This type of bra matches perfectly with lower cut tops and knits with square or wide necklines. Men find this style very attractive on women. A demi bra with 3 part cups has cups that are sewn in three places for superior support and shaping of the breasts. The advantage of 3 part cup bras is they help direct your breasts forward instead of letting them spread to the sides. Check out the 3 part cup demi bras at HerRoom.com and enjoy free shipping.
