How to Choose a String Bikini: Coverage, Fit, Ties & Sizing

A string bikini is defined more by its narrow ties and adjustable construction than by one fixed amount of coverage. A classic triangle top, halter top, micro triangle, traditional tie-side bottom, thong, and G-string can all use string construction while covering very different amounts of the body.

That distinction matters when you are shopping. The word string tells you how much of the garment is adjusted with ties; it does not automatically tell you whether the top is micro, whether the bottom is a thong, or how high the sides will sit on the hip.

At Los Angeles Apparel, our string-bikini assortment ranges from adjustable nylon-tricot classics to a more covered halter, micro nylon styles, metallic Lamé pieces, and leather fashion pieces. Because these products are sold as separate tops and bottoms, you can choose the silhouette and size of each piece independently.

This guide starts with coverage, then moves through top and bottom shapes, final-sale sizing, tie placement, mix-and-match decisions, materials, and care. The goal is simple: understand what each silhouette changes before you order.

What Makes a Bikini a String Bikini?

The most useful way to understand the category is to separate construction from coverage. String-bikini pieces use narrow straps or ties to adjust the garment at the neck, back, or hips. Those ties can support several different shapes.

Our classic String Bikini Top, for example, ties behind the neck and back. Its longer narrow cups can be scrunched for a more revealing placement or opened for a more traditional triangle shape. Our Halter String Bikini Top also belongs to the string-bikini family, but the halter shape provides more coverage than the regular string top.

The same principle applies below the waist. Our classic tie-side bottom, thong bottom, and Micro G-String all use adjustable ties, but they are not the same coverage category. The ties tell you how the garment adjusts; the front and back pattern pieces determine how much it covers.

Compare String-Bikini Top Styles

Top coverage changes with the size and shape of the cup as much as it changes with the ties. If you already know how much coverage you want, start there rather than beginning with color.

Classic Triangle: Adjustable Coverage Without Changing the Basic Shape

The classic triangle is the easiest place to start when you want a recognizable string-bikini shape. On our RNT3003, the cups are longer and narrow, the straps tie behind the neck and back, and the cups can be scrunched along the string. That means you can change how the fabric sits without changing to an entirely different neckline.

Halter: More Coverage in the Same Adjustable Family

The halter is the more-coverage option in our current string-top range. The shape stays narrow, but the top provides more coverage than our regular string bikini top and can be configured in more than one way. If a micro or classic triangle feels too exposed, this is the comparison to make first.

Micro Triangle: Smaller Panels, Not Just Thinner Ties

A micro top changes the scale of the fabric panels themselves. Our Nylon Tricot Micro Triangle Top is intentionally described as barely-there coverage, while our Lamé Micro Triangle Top combines a micro fit with adjustable ties and scrunchable cups. Choose these because you want a smaller coverage area—not because every string top is automatically micro.

Compare String-Bikini Bottom Coverage

Bottom terminology becomes clearer when you ask two separate questions: how much does the back cover? and how much fabric sits across the front? Rise and side-tie placement change the look again, but they do not turn a classic bottom into a thong or a thong into a G-string.

How to Choose Your Size When the Bikini Is Final Sale

Final-sale swimwear rewards a slower sizing decision. Adjustable ties can change position and tension, but they do not make every cup or bottom panel the same size. Start with the actual product information, then decide whether your goal is more or less coverage.

01Start With the Product Size Chart

Use the size chart attached to the exact style rather than assuming one string-bikini size behaves identically across classic, halter, micro, nylon, printed, and Lamé pieces.

02Compare the Model Reference

Model height, measurements when provided, and the worn size give you another point of reference. They are not a substitute for your own measurements, but they help show how the intended amount of coverage looks on a real body.

03Decide How Much Coverage You Actually Want

Two shoppers with similar measurements can still want different sizes if one wants a micro placement and the other wants more frontal or cup coverage. Make that decision before you interpret the size chart.

04Follow Product-Specific Sizing Notes

Do not apply one universal “size up” rule. Our RNT3002 Thong String Bikini Bottom specifically advises sizing up when you want more frontal coverage. Our Lamé V-Cut Thong carries the same type of product-specific guidance. That does not mean every string-bikini top or bottom should automatically be sized up.

05Choose the Top and Bottom Independently

If your preferred top size and bottom size are different, use them. A matching set does not require matching size labels, and separate sizing is one of the practical advantages of building a string-bikini set from individual pieces.

06Tie It Where You Will Actually Wear It

A bottom tied high on the hip can look and feel different from the same piece worn lower. A triangle cup pulled wide can cover differently from the same cup scrunched narrower. Judge the garment in the position you intend to use.

07Check Movement Before You Commit to the Fit

Once the ties are secure, sit, bend, raise your arms, and move through the positions you would normally use. You are checking whether the coverage stays where you expect it to—not whether the ties can simply be pulled tighter.

How to Tie and Position a String Bikini

String construction lets you fine-tune where a garment sits. The most secure fit is not automatically the tightest possible knot; it is the position where the garment stays balanced without pulling the fabric out of shape.

Neck and Back Ties

On triangle and micro tops, adjust cup position before you fully tighten the neck. Then use the back tie to set the band tension. If the neck is doing all the work, the top can feel unnecessarily tight even when the cups are not positioned correctly.

Scrunchable Cups

On styles with scrunchable cups, moving the fabric along the string changes the width of the cup. Narrower placement exposes more; spreading the fabric creates a more traditional triangle presentation. Make the adjustment symmetrically, then reassess coverage once the top is tied.

Side-Tie Bottoms

Set the front and back panels first, then tie the sides at the same general height. Our classic and thong string bottoms can be worn higher on the hips, but moving the ties upward also changes the angle of the leg line and how the front panel sits.

Secure Knots

Tie a knot that stays stable under normal movement and test it before swimming or wearing the garment for a full day. If a tie needs extreme tension to stay in position, recheck the size and placement rather than relying only on a tighter knot.

How to Build a Mix-and-Match Set

A string-bikini set does not have to match by silhouette. In fact, separating the top and bottom decisions often creates a better fit because you can control coverage in each area independently.

Understand the Materials Before You Mix Them

String describes construction, not fiber content. Our current assortment includes nylon-tricot styles, printed stretch versions, metallic Stretch Lamé, and genuine leather fashion pieces. Those materials should not be treated as though they have identical hand feel, care, or water use.

String Bikini vs. Thong Bikini vs. Micro Bikini

These words describe different things, which is why they can overlap on the same garment. Once you separate construction, neckline, and coverage, the names become much easier to understand.

How to Care for a String Bikini

Start with the sewn-in care label on the exact garment. The collection spans different fibers and finishes, so one rule should not be transferred automatically from nylon tricot to printed polyester, Lamé, or leather.

Our current classic nylon-tricot top, classic bottom, thong bottom, Micro Triangle Top, and Micro G-String product pages state that those pieces are machine washable. The printed halter is also listed as machine washable, but its fabric is a polyester-elastane blend rather than the nylon-elastane composition of the solid halter.

For Lamé, follow the exact garment label rather than assuming it should be washed exactly like the nylon pieces. For our leather bikini pieces, the rule is completely different: they are dry clean only and not water resistant.

When you are building a mixed set, check both labels. A top and bottom that work visually together can still have different material and care requirements.

Frequently Asked Questions

Choose the Coverage First, Then Build the Set

The easiest way to shop this category is to stop treating “string bikini” as one silhouette. Start with the top coverage you want, choose the bottom coverage separately, then use the ties to fine-tune placement and tension.

If you want a more familiar triangle direction, begin with the classic top. If you want more cup coverage, compare the halter. If the intention is a micro look, move to the Nylon Tricot or Lamé micro tops. Do the same below the waist: classic tie-side, thong, and G-string are three different coverage decisions.

Once the silhouettes are right, choose the material and color. That order makes the adjustable construction work for you rather than asking one word—string—to explain the entire fit.
