Underdays Reviews 104

Pretty and comfortable underwear. Fast delivery.

I think I've spent close to £200 on here now. Very soft briefs and cheekys, no riding up the cheeks or roll down my muffin top. Would say only the tank top is slightly fitting so not ideal for those of us with long torsos and a bit of armpit roll. But the matching thong was shockingly good during disco barre and washed + dried in time for 1.5h of sweaty ashtanga the following morning. No "wedgy" at all. If I was made of money I'd buy all my undies from them. Alas...

Love the material of these underwear. The sizing can be a bit off especially for tops for girls a bit more generous on the bust. Would I purchase again? Probably. Would I recommend? Definitely, despite being a bit pricey. You can find good underwear for cheaper.

The only thong I like! Could never find a comfortable thong but the activewear thong is super comfortable, you don’t even notice you have it on. Have it in every colour now and looking to grow the collection!

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 .

Found these randomly on insta & I'm such a convert !! So comfortable & I adore them

Want to make all my underwear Underdays!!!

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

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.

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.

Really comfy undies and very efficient service

This underwear lives up to the hype, so comfortable, no slippage and great styles and colours.

They're so soft and I love the colours! I especially enjoy the work out thongs, so good! Looking forward to the new colours coming out soon :)

Love the brand, underwear is soft and comfy and has a great fit, colour options are great although I miss the blush colour

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 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! 💕

Love the high waisted , so comfortable .
I recently ran a half marathon and wore under days , no rubbing at all . Have starting buying the everyday for my teenage daughters .
Please more colours in the high waisted .

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.

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!
