Smooth soft feel, and seamless.  Very durable.  I only wear soft cups with wires bcs I hate padding.  These bras feel great against your skin and give you such a natural look.

Update - Bra lasted only 3 months (all 3 of mine) before the wire poked thru the fabric in the middle of the chest and the elastic 'lace' began to stretch and get those rubber band type strings hanging from them.  I am ordering more because they are so comfy but wanted to note wear time.
