This is a gorgeous lace bra. It is not for sports or knits.
It is a very soft, comfortable bra with lots of attention to detail to keep it  comfy inside & out. The inside is soft lined fully.  A lace bra can be scratchy but not this one. Mind you, I still wouldn't wear it under a t-shirt because the beautiful lace texture will show.
I agree with some of the others that the band size runs a little big. I can usually wear a 32 or 34 but I really needed the 32 in this.
Other wise, it fits is well.
I was pleasantly surprised at the overall quality of this bra compared to the price. It feels & looks like a bra that would cost 3x  the price. I just received it so I can't address its durability but it looks very well made.
