I love my new bikini top. I have normally bra in size 70B so size S fits me perfectly. So so happy with the purchase. The material also feels comfy and you can tell it has been made from a good sustainable fabrics.
Ik heb een xs in de top (cupmaat 75B), in het broekje een maat s, als je tussen twee maten inzit, koop dan de grotere maat:)
Het is een mooie bikini, helaas niet geschikt voor een kleine omvang en grote cup! Ik heb maat 75E/70F en XL was veel te klein
