Description
The one that looks nothing like period underwear.
Margot is high-waisted and finished with a wide band of fine lace at the waist — delicate, detailed, the kind of thing you'd buy for a Tuesday and not just an occasion. It flatters every shape, and it holds.
Capacity is 30 ml, the equivalent of 3 tampons: made for medium flow, or for the start and end of a heavier one. Depending on your flow, you can wear it a full day with no saturation and no dampness.
The body fabric is a very fine nylon with a smooth, flat finish, so despite the coverage Margot stays invisible under clothing. It stores your flow without swelling.
Available in sizes XXS to 3XL. Our model wears a size S.
