It supports, separates, keeps things in place, creates a nice silhouette, straps don't dig into shoulders, nothing chafes, and it washes and dries nicely.  I own several now and they do what they're supposed to do for a plus sized woman and are durable.  I use them for work everyday and for exercise, very comfortable. I especially like the mesh insert at the top, it helps even more to keep a large bust in place and not fall out.
