Our verdict
The queen of pants, Sloggi’s Tai briefs offer amazing quality, comfort and value.

For soft, wedgie-free pants, these briefs from Wirarpa are hard to beat. They’re well cut to cover your cheeks and feature an extra-wide gusset to guard against hungry bums.

Our verdict
These supremely comfortable knickers from Innersy are made from thick, stretchy cotton and are generously cut on the tummy and bum for great coverage. They’ve got a 3-inch wide flat waistband with very light control, making them great for C-section recovery, as they’re gentle and supportive against your skin.

Our verdict
While Ann Summers may not be a go-to for everyday underwear, it’s certainly a great place to shop for special occasions.

"They are expensive, but I have pairs that are 10 years old and no end in sight. The colours and prints can be weird, but they will never, ever budge" - Brand recommended by Mumsnet user, dudsville
"Yes - Thunderpants! I LOVE them. My sisters and I buy them for each other as birthday presents!" - Brand recommended by Mumsnet user, 00feckingbollocks
Our verdict
With their bold patterns and retro fit, Thunderpants are in a league of their own. Made for coverage, they contain your whole bum, meaning you’ll never need to adjust your underwear and they won’t disappear between your cheeks. The high-rise waist sits just below your navel, and the cotton is soft and thick, so they’re really comfy to wear. Beloved for their bright and patterned knickers, Thunderpants also do plain black and white pairs.
9. Best high-waist women’s pants: M&S High Rise Microfibre Full Briefs
RRP on writing: £12 for pack of five | Buy now from M&S
Key specs
Material: Polyester, elastane and cotton | Sizes: 6 to 28
What we like
Ultimate comfort and coverage
Smooth microfibre fabric so no VPL
What we don’t like
Despite being polyester, the gusset is 100% cotton
What Mumsnet users say
"I have these pants! Actually I have three packs of them because I asked my mum for 'big pants' for Christmas (she asked and I'm almost 50 btw!) and she lost track of what was in her online basket. They are so, SO comfortable! Best pants ever, #livingmybestpants" - recommended by Mumsnet user, OldTinHat
Our verdict
What’s soft, stretchy and comes right up to your belly button? Big pants from M&S! These are the ultimate for comfort and coverage, plus the smooth microfibre fabric means not a whisper of VPL. For those horrified at the thought of polyester knickers, rest assured the gusset is 100% cotton.
10. Best lace briefs: M&S Lace & Modal Brazilian Knickers
RRP on writing: £16 | Buy now from M&S
Key specs
Materials: Polyamide, elastane, cotton | Sizes: 6 to 28

What we don’t like
Advice to size up when ordering
What Mumsnet users say
"Another vote for M&S Brazilians. Perfect fit on the bum" - recommended by Mumsnet user, Starlightlady
"I'd recommend Marks & Spencer. I'm sure I own most of the Brazilian styles they've done in the last few years" - Recommended by Mumsnet user, DieShottin93
Our verdict
The second appearance in our round-up for M&S, their Brazilian knickers are almost as legendary as their high-rise full briefs. The lace trim makes them flattering and comfortable to wear, and the low-rise waist is great for those who like a skimpier fit. This style features cheeky lace on the bum, a 100% cotton gusset and the signature Brazilian cutaway back.
11. Best seam-free women’s pants: Victoria’s Secret Seamless Thong
RRP on writing: From £50 for pack of three | Buy now from Amazon
Key specs
Materials: Nylon and elastane | Sizes: S to XL
What we like
Completely seam-free
Stretchy, tiny and lie flat against skin
What we don’t like
Made from manmade fabrics
What Mumsnet users say
"Victoria’s Secret! Their no show/no VPL ones are amazing and last really well and don’t lose their elasticity. Evangelical about them and never get pants anywhere else" - Brand recommended by Mumsnet user, Elletine
"Exactly what I was going to suggest. In fact at VS underwear I've ever had has been brilliant. They often have offers on" -Brand recommended by Mumsnet user, Cam2020
Our verdict
Possibly the world’s most invisible pants, these seam-free thongs from Victoria’s Secret are stretchy, tiny and lie completely flat against your skin. They’re made from manmade fabrics, so they’re not as breathable as cotton styles, but the raw edge and super stretchiness ensure a snug fit and zero VPL.
12. Best women’s boxer shorts: Calvin Klein Modern Cotton Boy Shorts
RRP on writing: £20 | Buy now from Amazon
Key specs
Materials: Cotton, modal, elastane | Sizes: XS to XL
What we like
Smooth, comfortable fit
A closer, more secure fit
What we don’t like
Price tag
What Mumsnet users say
"I have some Calvin Klein shorts which I got in the sale and they are great" - Brand recommended by Mumsnet user, ZaraW
Our verdict
If labels are your thing, the iconic waistband on these Calvin Klein women’s boxers is a big selling point. But Calvins aren’t just for show - they’re made from a cotton modal mix that offers a really smooth, comfortable fit. While many Mumsnetters have discovered how comfortable men’s boxer briefs are, these are cut for a woman’s body and offer a closer, more secure fit.
How to buy the best women’s pants
Everyone is different, so consider what’s comfortable and practical for you. A full, high-rise brief gives maximum coverage, while a Brazilian or a mid-rise brief has a more flattering look and less fabric. Sizing up is a good move, as there’s nothing worse than too-tight pants.
What style of knickers is the most flattering to wear?
A no-VPL style will keep you comfortable without interfering with the silhouette of your outfit, and for looking good in your scanties, Brazilian style knickers are cut to make your bum look its best.
What’s the best material for women’s pants
Cotton with a hint of stretch is the best fabric for women’s knickers. Cotton is breathable while the stretch from elastane or spandex gives a snug, comfortable fit and offers ease of movement.
What are the best women’s pants to buy?
The best women’s knickers are made by pants experts Sloggi. Their Tai briefs are our pick of the pants, because they tick all the boxes in terms of comfort, fit and quality.
