Women’s Underwear NZ

You’ve been asking….and it’s finally here New Zealand

You’ve asked. You’ve hinted. Some of you even begged. And now, it’s finally here. Our very first SWAG women’s collection has arrived.

Featuring bold prints, everyday essentials and bestselling character designs in coordinated sets, there’s something for every style. Choose from boyleg briefs, bikini briefs and crop tops because ordinary has never really been our thing.

We’ve officially entered our women’s era, and trust us, comfort has never looked, or felt, this good.

Whether you’re looking for everyday essentials or fun statement pieces, our women’s underwear collection is designed for Kiwi women who don’t want to compromise on comfort or style.

Find your perfect fit with SWAG

No matter your shape or size, finding the right fit makes all the difference. That’s why our women’s underwear collection has become a favourite with women across New Zealand looking for comfortable everyday essentials.

Whether it’s your curves, your bust or your hips, every woman deserves underwear that fits properly and feels great. And when it fits well, you’ll spend less time adjusting, and more time getting on with your day. That's why women across New Zealand choose SWAG for comfortable, supportive underwear that fits beautifully.

Wearing a crop top, bikini brief or boy shorts that’s too small can lead to chafing and discomfort, while sizing up too much can leave you with excess fabric that bunches, shifts and never really sits just right. The SWAG women’s range offers sizes from S to XXL, and we recommend checking in on our size guide to find your perfect fit before ordering.

When you’ve found the right size, you’ll know. Say goodbye to underwear riding up, shifting, and constantly needing adjusting. Just all-day comfort and confidence.

Found your fit? Then head over and check out our range of colours and playful prints to add a little extra SWAG to your underwear drawer. From everyday essentials to bold statement prints, we're proud to offer comfortable underwear for Kiwi women.

Frequently Asked Questions

Why should you wear a crop top bra?

A crop top bra combines comfort, support and style in one easy-to-wear design. If you’ve ever found traditional bras uncomfortable because of underwires or clasps digging in, a crop top gives a more comfortable alternative. Designed for everyday wear, workouts, or just relaxing at home, our crop tops provide a smooth, supportive fit that moves with you. Whether you’re heading to the gym or spending a laid-back weekend, they’re made to keep you comfortable all day long.

What’s the best fabric for women’s underwear?

Our micro-polyester blend is soft, lightweight and breathable, making it ideal for everyday wear. Unlike cotton, it doesn’t absorb moisture; it wicks it away, helping you stay cool, dry and comfortable throughout the day. Whether you choose a crop top, bikini brief, or boyleg, our premium fabric offers the perfect combination of stretch, comfort, and durability for all-day wear. It’s one of the reasons our women’s underwear has become a popular choice for customers throughout New Zealand.

Does micro-polyester cause irritation?

Not at all. Our premium micro-polyester blend is designed to feel soft, smooth and gentle against your skin. Lightweight and breathable, it offers all-day comfort without sacrificing durability, so you can wear it all day, every day.

How often should you replace women’s underwear?

How often you replace your underwear depends on how frequently you wear it and how well you care for it. As a general guide, it is good to refresh your collection every 6 to 12 months. Whatever style you prefer, replacing well-worn underwear helps provide lasting comfort, support and hygiene.

How do you know when to replace women’s underwear?

There are a few things that will let you know when it is time to replace your favourite knickers and crop tops. These include:

• Loss of elasticity or support
• Faded colours
• Thin, worn or patchy fabric
• Stubborn stains that won’t wash out
• Lingering odours, even after washing

If your underwear is showing any of these signs, it’s a good time to treat yourself to a fresh set.

Should I wear a bra every day?

This comes down to personal comfort, but we’re going to say it isn’t necessary. While bras offer some great support, sometimes you just need that bit of extra comfort that comes with going braless. Our women’s crop tops are a great middle ground for when you need to pop a bra on, but don’t want the full underwire deal.

How to wear crop tops?

Women’s crop tops are so incredibly versatile and easy to style. Wear them under a sheer top for a pop of colour, layer them beneath some overalls, or pair them with your favourite workout wear for some time sweating it out at the gym.

With a wide range of prints and colours to choose from, you can show off your personality with pop culture favourites, beloved characters and even your Hogwarts house colour!

Do I need special maternity wear?

Pregnancy is a special time and having comfortable, supportive underwear as your body changes becomes even more important. Soft, stretchy fabrics like our micro-polyester blend move with your body and help minimise irritation throughout the day.

When choosing your pregnancy underwear, look for styles with a flexible waistband that sits comfortably either over or below your bump, depending on your preference. The right fit will provide gentle support without feeling restrictive, helping you stay comfortable as your baby grows.

How to avoid panty lines?

For a smooth, no-visible-panty-line look, choose seamless underwear or styles made from our soft micro-polyester blend. Designed to sit comfortably against your skin without bulky seams, they’re the perfect choice under leggings, dresses, skirts and fitted jeans, giving you a sleek, confident finish no matter what you are wearing.

Is lace underwear good for you?

There is no denying that lace underwear looks beautiful and feels luxurious, but it isn’t always the most comfortable choice for everyday wear. Depending on the design and fabric, lace may be less breathable than materials like our soft micro-polyester blend, which is lightweight, moisture-wicking and designed for all-day comfort.

Should I buy women’s underwear online?

Absolutely! Shopping for women’s underwear online is an easy and convenient way to refresh your top drawer. At SWAG, you’ll find detailed size guides and helpful fit information to make finding the right size simple. Browse our collection of crop tops, boylegs and bikini briefs from the comfort of home, with delivery available throughout New Zealand.

Are moisture-wicking women’s underwear good for working out?

Moisture-wicking underwear is perfect for exercising. Our soft micro-polyester blend helps keep you cool, dry, and comfortable whether you're at the gym, exploring one of New Zealand's beautiful walking tracks, or simply enjoying a stroll along the beach. Pair your favourite SWAG crop top with matching underwear for a supportive, comfortable combination that moves with you through every squat, stretch or throw of the ball.

Which underwear style works best for a special occasion?

For special occasions or when wearing more fitted clothing, seamless bikini briefs are a great choice. Designed to sit smoothly under your clothing, they help minimise visible panty lines while keeping you comfortable throughout the day.

When is it suitable to wear boylegs?

The ultimate in comfort! If you’re after the perfect combination of comfort, coverage and support, you’ll love our boyleg underwear. They provide a little more coverage than bikini briefs and are ideal for everyday wear.

Are full briefs supposed to feel tight?

No, they are not. Your underwear should feel secure and comfortable without digging in, rolling down or leaving noticeable marks. The right fit comfortably hugs your body, stays in place and provides coverage without pinching or constantly adjusting.

What’s the best way to stop women's briefs from riding up?

The right fit is so important. Underwear that is too small can ride up and feel restrictive, while a size that is too large may bunch, shift or lose its supportive fit. Underwear with soft, stretchy waistbands that sit comfortably under your outfit without digging in is best.

Can I mix and match underwear in the same collection?

You can mix and match all you like! Our women’s selection is designed to be as unique as you are, so you can mix and match your favourite crop tops, women's briefs or boylegs to create a look that is uniquely yours.

How do I keep my comfortable underwear in the best condition?

We recommend washing your SWAG wear in cool water, using a gentle detergent and allowing it to air dry where possible. This helps protect the elastic, maintain softness and extend the life of your favourite SWAG pieces, so they're ready for wherever life takes you around New Zealand.
