Soft and comfy
Size: XX-Large, Color: Black
Nice, soft, fits pretty well although space between cups is a little oddly wide which I’ve never had an issue with before. Still, it’s cotton and comfortable.

Nicely made
Size: Medium, Color: Black
I appreciate the organic material but it’s just a bit itchy for me I wonder after a couple of washings if it’ll soften up.
