What is a crotchless bikini?

A crotchless bikini is a bikini-style set or bottom designed with an open construction or intentionally minimal bottom coverage. It is searched as crotchless bikini, crotchless bikinis, crotchless swimwear, crotchless swimsuit, crotchless bathing suit, and crotchless micro bikini.

Crotchless bikini vs. micro bikini

A micro bikini is about minimal fabric and tiny coverage. A crotchless bikini is about the open-bottom design. Some shoppers want both: a micro silhouette with a crotchless or ultra-revealing cut.

How should it fit?

• Waist or hip straps should feel secure without cutting in.
• Adjustable ties help fine-tune the fit.
• Stretch fabric should recover after movement.
• When between sizes, check the size chart and consider sizing up for comfort.

How to style it

Pair bold swimwear with a sheer cover-up, beach robe, oversized white shirt, wrap skirt, kimono, or sandals. Browse crotchless bikinis, crotchless micro bikinis, and women's swimwear for related styles.

What to check before buying

Review sizing, return eligibility, fabric, lining, adjustability, product photos, and care instructions before ordering.
