Monokini Swimsuits: One Piece, Cut Like Two

What Is a Monokini?

What Is a Monokini?

A monokini is a one-piece swimsuit with cutouts or open panels that make it read like a bikini — a single garment with a two-piece look. The torso is connected, but the open sections break the line into shapes.

The monokini sits between a one-piece and a bikini: it keeps the single construction while borrowing the bikini’s open look. Cutouts, sliding triangles, low backs and string panels are the usual ways the effect is built.

One piece, cut like two — the construction is single, the look is open.

Monokini vs. One-Piece vs. Tankini

Monokini vs. One-Piece vs. Tankini

Three silhouettes sit close to the monokini, and the borders are clean:

  • One-piece — a single garment with a continuous line.
  • Monokini — a one-piece with cutouts or open panels that read like a bikini.
  • Tankini — a two-piece with a top that covers to the waist.

The monokini is still one garment; the tankini is two. When shop titles blur the lines, check the construction in the photos — connected torso means monokini or one-piece.

Monokini cuts the one-piece; tankini splits it into two.

The Styles in This Collection

The Styles in This Collection

Monokinis show up across these silhouettes:

  • Cutout sliding-triangle styles
  • Low-back and backless string monokinis
  • String and micro thong monokinis
  • Micro striped monokinis
  • Halter and strappy monokini tops

Prices run from about $19 to $38, and sizes from XS to XL with a few one-size pieces.

Pick the cutout first — the open panels are the monokini’s signature.

Wearing a Monokini

Wearing a Monokini

Monokinis work across pool, beach and resort settings — the cutouts are the design, and most venues accept them. For bolder open-panel styles, check the venue ahead and bring a cover-up.

Fit matters with open panels: read the size chart, and check the material notes for how the fabric holds — cutouts shift differently than solid panels, so the hold of the fabric matters more.

Venue first, fit second — the cutouts are the style, the fit is the function.

How to Choose & Care

How to Choose & Care

Work through four decisions:

  • Open panels: cutout, low-back, string or strappy
  • Coverage: how much the panels open the torso
  • Fabric: nylon, mesh or textured — hold differs
  • Occasion: pool, beach or resort

For care, hand-wash in cold water and dry flat in the shade. Sizes run XS to XL with some one-size pieces — check each listing’s chart.

Panels first, coverage second, venue third.

Frequently asked questions

What is a monokini?
A monokini is a one-piece swimsuit with cutouts or open panels that make it read like a bikini — a single garment with a two-piece look. The torso is connected, but the open sections break the line.
What is the difference between a monokini and a one-piece?
Both are single garments. A one-piece has a continuous line; a monokini has cutouts or open panels that break the line and read like a bikini. The construction is the same; the panels differ.
What is the difference between a monokini and a tankini?
A monokini is one garment with open panels. A tankini is two pieces — a top that covers to the waist and a separate bottom. One-piece construction versus two-piece is the key difference.
What is the difference between a monokini and a bikini?
A monokini is a single connected garment with cutouts. A bikini is two separate pieces, a top and a bottom. The monokini mimics the bikini look without splitting into two garments.
Are monokinis comfortable?
Comfort varies by fabric and fit. Open panels shift differently than solid ones, so the fabric's hold matters more. Check the size chart and material notes on each listing.
What sizes do monokinis come in?
Styles in this collection range from XS to XL, with a few one-size pieces. Because cutouts change how a style fits, check the size chart on each product page.
Can you swim in a monokini?
Yes, for casual swimming and beach days. Open panels hold differently than full styles, so check the fabric's stretch and the listing's fit notes for active use.
How do you care for a monokini?
Hand-wash in cold fresh water and dry flat in the shade. Open panels and fine trims are delicate — avoid dryers and hot water, and check each listing's care notes.
