Choosing a women’s bikini: fit, fabric and how you’ll use it

Buying a women’s bikini seems straightforward – until the top slips, the bikini bottoms feel too tight or the fabric loses its shape after a few swims. You can also end up with the wrong bikini underwear or bikini-line grooming products if you rely on marketing claims that don’t tell you much about everyday use.

Three common pitfalls are worth watching out for:

• Choosing a size based on your clothing size: an XS, M, L or XL bikini can fit differently depending on the style. Always check the size guide and look for adjustable straps or fastenings.
• Focusing only on colour and style: a black women’s bikini is versatile, but the fit, lining and support have the biggest impact on comfort.
• Using products for sensitive skin without preparing first: wax strips and hair removal cream for the bikini line come with clear safety instructions. Just because the packaging says a product is suitable for the bikini line doesn’t mean it’s suitable for irritated or damaged skin.

What should you look for in a women’s bikini?

1. Fit and sizing

Don’t just look at XS, M, L or XL. Check:

• the band measurement under the bust;
• whether the halterneck straps are adjustable;
• the coverage and cut of the bikini bottoms;
• the proportions of the top and bottoms.

A halter bikini with straps that tie behind the neck and at the back can be adjusted to suit you. This is useful if you’re between sizes. Bear in mind, though, that a halterneck style can put more pressure on your neck if the straps are tied too tightly.

An integrated push-up effect can change the appearance of your bust. Check the product description and the construction of the cups. A push-up bikini won’t necessarily give you more support when swimming or exercising.

2. Fabric, seams and care

Check the fabric composition and care instructions. Elastane usually provides stretch, while nylon or polyester is often used for swimwear that needs to dry quickly. The exact composition determines how a product feels and how it should be cared for.

Pay particular attention to:

• flat or soft seams;
• enough stretch without excessive pressure;
• washing instructions on the label;
• advice on drying and exposure to chlorine or salt water.

For bikini underwear, a smooth finish is useful under close-fitting clothes. For example, the Calvin Klein bikini briefs in the product information provided are made from 82% recycled nylon and 18% elastane, with a mid-rise fit and flat leg openings. These are verifiable specifications, and tell you more about the product than general terms such as “extra luxurious”.

3. How you’ll use it and personal care

First, decide what you need the product for. A stylish set may be all you need for sunbathing and a relaxing swim. For more active swimming, surfing or exercise, a secure fastening, adjustable straps and well-fitting bikini bottoms matter more.

There are several options for personal grooming:

• Bikini-line wax strips: suitable if you want to remove hair from the root, but follow the warnings and test the product as directed on the packaging.
• Bikini-line hair removal cream: check how long you can leave the cream on. Don’t leave it on for longer than instructed.
• Women’s bikini trimmer: a practical choice if you want to trim hair without using wax strips or cream. Check the attachments, battery or USB-C connection, and whether the device is designed for wet or dry use.

Don’t use wax or cream on sunburnt, irritated or damaged skin. The Veet products below also advise you to follow the instructions and safety information on the packaging.

Frequently asked questions about women’s bikinis

How do I know whether I need a size M or L bikini?

Measure your bust, waist and hips, then compare your measurements with the size guide for the specific brand. A halterneck bikini may offer extra room for adjustment, but it won’t make up for choosing the wrong size. Also check whether the top and bottoms come in the same size.

How long does a women’s bikini last?

How long it lasts depends on the fabric, how often you wear it and how you care for it. Rinse swimwear in clean water after exposure to chlorine or salt water, follow the care label and avoid high drying temperatures unless they’re permitted. Loss of elasticity, fading and permanent distortion are signs that it may be time to consider a new set.

Which is more practical: wax strips, cream or a bikini trimmer?

It depends on your preference and how your skin reacts. Wax strips remove hair from the root, according to the product description, while cream dissolves the hair and a trimmer tidies it up. Always check what the product is intended for, test new products on a small area if the packaging advises you to, and follow the safety instructions.
