I used to wear bras with no underwire but the support factor of most is pretty abysmal, so for years I have reconciled myself to underwires. Some are reasonably comfortable but then I discovered this bra.  I have never liked padding beyond  just enough to suffice under thinner fabrics such as T-shirts. I immediately hoarded several pairs of this one in case they disappear from the market!
For the average size I am (34B) this style  is perfect----comfortable, plenty of support, and looks great under everything.
