super soft, stretchy and non toxic material

I initially came across Underdays coming up to 9 months - I made my first order, rather large one considering I didn't know the brand but what stood out to me were the none toxic material, and as someone who has fought ovarian cancer recently it was very important. I love how smooth the material is, so much so it literally feels like I'm wearing nothing, which in turn also means the fabric is stretchy too.
I've just made my second purchase with their limited edition colours :)

fabulous shapes , styles that work with any outfit .

Comfort is key - you almost forget that Underdays are part of your body .
Colours are always exciting but there are always functional colours for those that want them .

Sport girl underwear probs

I really struggle with underwear that doesn't irritate, especially when playing sport. These do a good job of being kind to my sensitive areas and I think so far so good, the branding part has come off after washing (have owned them for around 3 months). That doesn't bother me too much but I think it isn't great for the price

Amazing

Having converted to underdays around 6 months ago, I can’t wear any other underwear now!

The quality is amazing, they are so breathable, comfy, and stay in place all day. I particularly love the work out thongs which don’t move or roll up at all when working out!

Whilst slightly on the pricy side they’re definitely worth the investment.

The best thongs in the world

I love Underdays. Honestly can never go back to wearing any other pants!! They are so soft, super breathable, and are the comfiest thong to ever exist. I've been wearing Underdays pretty much since they first launched and they have stood the test of time - I was quite surprised by some of the negative reviews that said they didn't, mine are good as new! Love love love.

I like this brand but…

I like this brand, I like them a lot.
It feels like though they don’t like me and girls like me who love high waisted pants 🤷🏻‍♀️
Most of the new colours don’t go on the high waisted pants, not the colourful sets as well.

The quality is great so I’m like a dumb girl coming back for the black/grey ones, crumbs of attention that I’m still pecking like a dove.

My daughter and I discovered Underdays…

My daughter and I discovered Underdays on Instagram and we’re now complete converts! We absolutely love the comfort and quality of your underwear — it’s perfect for both the gym and everyday wear. The fit is so flattering and soft, it feels like it was made just for us.
Our only wish is that the high-waisted styles came in more colours, because they’re our favourite! We’re just about to place another order so we can swap out all our old underwear for Underdays.
Thank you for creating something that’s both stylish and comfortable — we’re obsessed! 💕

Not how they advertise

Had the underwear for about a year now - always wash and dry as per the instructions. They started off comfortable. But now, the seams are folding, which cut into my skin and cause a lot of discomfort, and some stitching coming undone. The workout thong has never looked seamless, creates a 'muffin top' look under Lululemon Align leggings.

Don't trust their advertising - I've had M&S pants that have lasted A LOT longer, more comfortable, and are still in perfect condition. And a lot cheaper.

Highly recommend!

The underwear is so much more comfortable, super buttery, barely there vibes. I've have slowly been switching out my old knickers and especially love the high waisted at night time. Would highly recommend anyone to make the switch. Definitely worth the price!

A lovely company with amazing items

A lovely company with amazing items. I love this company and cannot recommend them enough! The quality of the items is great and they are so comfy, I will never go back to supermarket underwear. I love the limited edition colours and the embroidered sets.

Absolute gems!

I have been telling everyone I know to buys these. They are so well made. All of the pairs I have bought have lasted great wash after wash. I have bought as gifts for my knicker wearing relatives and they love them too. The size range is great and I find them to be true to size too. I only found the website whilst looking for a company that made knickers with a longer gusset, as I was fed up with the high street stores ( probably male designed) knickers. I am so glad to have found these absolute gems and have been buying them ever since, having thrown out all my other knickers. They are so soft & comfortable to wear no stupid labels or any other irritations. Do not hesitate to buy, even if they are pricey they are worth it.

Workout thong great for running

Although not advertised for running, I bought some workout thongs for running (I hate lined shorts, far too hot and uncomfortable). These are a revelation. I’ve used them on many runs now, up to four a week and distances up to 20 miles, very comfortable and keep you cool. Lasting well too, only issue with first pair I put them in the washing machine and stitching went bobbly. Simple solution, just wash them by hand, no further problems. Now my go to underwear for running.

After just one year- clothes falling apart

After just one year, the stitching is all falling out, the top looks 15 years old, not one. It looks like it’s completely fallen apart and is unwearable. Don’t believe any of the sustainability or high quality claims from this company, it’s rubbish and goes to show in the fact they have such a short warranty on their clothes.
