Fabric change?

Been shopping this brand since they had the pre-drop for their first leggings. Love the cut in comparison to the Tommy bras, but what is going on with this fabric? Is this not also for compression? I have many of their Tommy and Paloma bras and this is so thin in comparison. Fabric composition says it's the same though. Nipples definitely show. The elastic band is also structurally very different.

Comfy

Fits soft and comfy. Wish the straps had another inch of length or were somehow adjustable.

Love the bra, very comfortable!
