Wonderful bra

I love this bra! I wear it the whole day and I barely notice I have anything on. It's also super soft and looks beautiful.
They're on a smaller size though, so definitely size up (I usually wear XS and this bra in size S fits me perfectly). I'm not sure I'll go back to buying regular bras, as I wear now this one to work as well.

The size doesn't fit me

I bought the S size as all my tops are XS-S.
The cup is fine, but the band is so tight that I can barely brief! Once I tried to wear it all day, hoping it would stretch, but I end up with a creepy visible mark on my body.
