Frequently asked questions

Your questions, answered

Absorbency, size, materials, washing: everything you need to know before choosing your period panties.

Can menstrual panties be seen under clothes?

No: Séléné, Artémis and most Smoon models are made without seams and don't show under fitted trousers or a dress, thanks to a second-skin microfibre. Under light-coloured clothes, choose a beige panty.

Which menstrual panties to wear under leggings?

Luna and Diane have a no-line finish that doesn't show, even under leggings or fitted shorts. The Vega sports thong and the Aphrodite thong, cut higher on the leg, are the most discreet.
