I'm stacked. After having a kid I'm now an I and it's a pain in the back. Underwires are not for me unless I'm dressed up because really they're not comfortable and kiddo hates when I have an underwire bra on. She says (she's almost two) that she can't hug me close enough because my shirt is hard (lol) I've been to that certain intimacy store and even had bras custom made for me, but this one is more comfortable than ones I've paid $165 for! And it holds up to multiple washings well. I'm pretty active and do yoga and agility with our border collie (believe me, you run almost more than the dogs!) and this is the bra I feel most secure in. Just an odd side note? I bought this in white, but it doesn't fit or feel as good as the black. Different material makes it not nearly as nice. And they don't last forever and certainly aren't sexy, but they are comfy.
