At Monday, we strive for consistency in every collection to ensure you feel your best every time you wear our pieces. However, due to the unique qualities of each fabric, slight variations in fit may occur and cannot always be directly compared. Since certain styles are crafted from different materials, differences in fit are to be expected.

If you match any of our beachwear with this style please keep in mind that the fabric can offer a slightly different shade in our swimwear and beachwear, therefore an exact color match cannot be guaranteed.

Hand wash cold. Lay flat to dry indoors.
