Basic ladies panties in breathable cotton. Comes in several lovely colors, of which I purchased many. The lace might show through under closely fitting dress material, but I'm able to wear these under dress pants and jersey fabric dresses without any creases showing through.
Underwear great. Packaging terrible. I ordered 6 items (5 exactly the same + 1 in a different color) and they were delivered in 3 separate packages - all plastic. And each item was also in an individual plastic bag. I wouldn’t have ordered if I would have known the environmental impact of my six tiny items.
