Buying another package
Size: Large, Color: Multicoloured D (5-pack)
Oh my gosh, I love these!!! They are very comfortable and not overly tight. The material is so thin and breathable, very comfortable. Love the colors. Am buying another package! I'm in perimenopause and these definitely keep me cooler than my tradition cotton underwear.

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.
