LA SIRENE 鏤空高腰比基尼泳褲

I was worried a high waist would look matronly but the cutout at the lower back keeps it fun. The Italian swim jersey feels thick and held its shape after a full day at the pool.

I wore this for a full beach day and the high waist stayed put without digging in. The lower back cutout is the part everyone noticed, and it looks way more expensive than it cost.

The double-lined fabric really does smooth things out—no digging or bunching when I sit down. The lower back cutout is a fun surprise without making the fit feel fragile, and it stayed put through a whole beach day.
