Are underwire bras better than non wired bras?

It depends on what size cup you have. Most people agree that if you have a C-cup or bigger, you need underwire.

A great alternative to underwire is to get fit for a custom fitted bra, which replaces the underwire with a second layer of stiff fabric, supporting the breast from underneath. These Bras will last up to 4 times longer than an underwire bra.
