High-cut. Backless. Open crotch. Four colours — Pink, Black, Yellow, Blue.
The cut that does the talking.
What it is
A one-piece that wears like lingerie. And photographs like a fashion statement.
The Fuchsia Fantasy Monokini is a high-cut, backless one-piece with an open crotch — designed for the bedroom, boudoir shoots, or anywhere confidence is the point. The cut sits high on the hip to elongate the leg and the backless design leaves most of the torso exposed. Four colours: the fuchsia pink is the original, Black, Yellow, and Blue round out the range. Five weight-based sizes from XS to XL — pick the one that matches your weight range, not a number on a chart.
Why this piece
Three details that define it
— No. 01
High-Cut Leg Opening
The leg opening sits at the very top of the hip — a cut that extends the line of the leg from the first glance. It's the defining silhouette of this style and the reason it photographs so well from every angle.
— No. 02
Backless Design
The back is fully open — no panel, no closure, just skin. The front holds in place with thin string ties at the neck and the structure of the high-cut body. The backless cut is what turns this from swimwear into something else entirely.
— No. 03
Open Crotch Construction
The opening is sewn into the seam with finished edges — no raw cuts, no fraying. It sits flush when worn and doesn't shift during movement. The crotchless design is discreet in the cut but deliberate in the intention.

Beautiful design and very elegant. It made me feel confident the moment I put it on — the cut is incredibly flattering and it photographs even better than the product images.

Bought this as a surprise and it worked perfectly. The look is stunning and the quality is far better than I expected. She gasped when she saw it on herself in the mirror.

It fits perfectly and makes me feel so confident and sexy. The high cut is exactly what I wanted — really flattering on the hip. Would definitely order again in another colour.

Four colours, five sizes
Pick the colour. The cut does the rest.
Pink is the original — the fuchsia that started it. Black is the most versatile. Yellow is bold. Blue is unexpected. All four share the same high-cut, backless, open-crotch construction. Sizing is weight-based: choose the range that includes your weight and the stretch fabric handles the fit from there.

Common questions
Before you order
What's the difference between XS and S — they overlap?
XS is cut for 90–110 lbs and S for 90–115 lbs — yes, the ranges overlap at the lower end. If you're 90–110 lbs and prefer a very snug, minimal fit, choose XS. If you want slightly more give or are closer to 110–115 lbs, go with S. If in doubt between any two sizes, always size up.
What exactly is a monokini? How is it different from a one-piece swimsuit?
A monokini is a one-piece cut with significant skin exposure — typically high-cut legs, a backless or open back, and minimal fabric coverage compared to a standard swimsuit. This one is specifically designed as a lingerie piece: the open crotch and backless cut make it intimate wear, not poolside swimwear.
How does the open crotch work — will it be obvious when worn?
The opening is built into the seam at the crotch with clean, finished edges — it doesn't fray or gap unintentionally. From the front it reads as a high-cut monokini. The opening is only apparent from the appropriate angle or when you choose it to be.
Is the fabric comfortable — does it dig in at the leg?
The stretch fabric adapts to the body rather than cutting into it. The high-cut leg opening sits at the hip, not the thigh, so there's no elastic band pressing into skin. Customers consistently mention the fit as comfortable for extended wear.
What will show on my bank statement?
Your statement shows "LN Goods" — not the store name, product name, or any category. Packaging is plain with no external branding.
