Best underwear for women: At a glance


How to choose the best underwear for women

One of the most important factors to consider when buying underwear is the style you’re after. How will they fit? What kind of coverage do they offer? Different styles offer different fits, so it’s important to pick a style that will suit your body shape.

What types of women’s underwear are available?

Some of the most common styles of knickers include:

Briefs: These are the most common type of knickers. In the past, this style has had a reputation for not being particularly flattering, but this isn’t the case now. Waist sizes come in low-, mid- or high-rise options for an optimal fit. Briefs offer full coverage and work under most outfits, from gym clothes to a favourite pair of jeans.

Bikini: Similar to briefs, bikini underwear has higher-cut leg holes. Also known as Brazilian cut, they sit low on the hips, which, in combination with the high-cut legs, makes legs appear longer.

Thong: A good option for eliminating VPL (visible panty lines), thongs offer basically no coverage over the bottom. This makes them ideal for tight-fitting clothing.

Cheeky: A fun combination of briefs and thongs, cheeky underwear provides partial bottom coverage, showing a little bit of skin. In other words, you get bottom support but without an abundance of fabric.

French cut: This style offers full coverage, with a high waist and high-cut leg holes that typically reach just above the widest part of the leg.

Seamless: This isn’t necessarily a style of underwear, but a good quality to consider. Seamless underwear doesn’t result in visible panty lines, which allows you to wear even the most body-hugging clothing without showing off what’s underneath.

Note that there are too many styles for us to highlight each one in our recommendations. But many items on the list can be found in multiple styles to best suit your preferences.

What else should I consider when buying women’s underwear?

Take into account your body shape and how the underwear will fit you. If you have a round bum and choose low-rise knickers, chances are you won’t get the bottom coverage you’re looking for.

Consider the type of fabric, too. Your underwear should at least have a 100% cotton gusset for breathability and moisture wicking. Cotton underwear is very common, as are microfibre and nylon options.
