A strapless push-up bra may not be your everyday bra, but it can make all the difference with some clothing. Push-up strapless bras are especially useful with evening wear and body-baring tops. The graduated bumps in a push-up bra are structured to lift breasts and enhance cleavage. Adding strapless design to that provides great versatility.
If you remember the days of tugging at strapless bras to keep them up, things have changed. New fibers and technology allow for lightweight styles that have some type of silicone along the sides to keep the bra up. Most styles, push-up especially, will have underwires and possibly some boning as well. Modern push up bras provide a natural youthful shape. Some even come with clear convertible straps to make them an even more useful lingerie wardrobe addition.
