Underdays Avis 

I really love the product here. However they use Evri delivery service which did not deliver my package, and when I asked for a new package to be sent out, there was much resistance in doing so. I also am now waiting for the new package, which I believe is lost as the website tracking shows it should be delivered a week ago, and no update. Customer service again has been reluctant to believe that Evri is an issue, and I'm quite annoyed with having to chase about my package, when it is wildly known how terrible Evri is. It's been a month and I still don't have my package and continue to have to chase customer service. This has been such a hassle and stressful for, and really had no apology (just told be be patient) or anything useful to help redeem the situation. It was a big order, so it's unacceptable to be out of the money with no products in my hand. I think brands need to be more accepting that Evri is not a great service, packages DO get lost, and the pressure should not be on customers to be patient.

I’ve been slowly building up my collection, swapping Underdays from other brands, they are super comfortable to wear on a daily basis but have noticed with the newer colours this year the sizing and feel has slightly changed. (Black/pink stitching and grey)

The absolute best underwear I've ever had. no discomfort or chafing, just cloudy-soft elegant everyday wear. Would love to see some more strong jewel tones, the current berry colour is amazing and rich, would love to see some deep forest greens/emeralds etc.

The material is incredibly soft. It’s now the only brand I wear to avoid any irritation or sweating. Everything feels gentle on the body, and the fit is both comfortable and sexy. I love the design of the top, it’s super cute. However, the small size on the top feels a bit too tight on me, even though I have a very small chest. For reference, I wear a size small in the underwear and the fit there is perfect.

I love the fabric, my thong are extremely comfortable. What I love about the product is that is fits my pear shape bottom better than any other product.
One of the light colour pieces was stained by my period, I was so horrified. But to my surprise I was able to remove the stain very easily with cold water and soap.
Love them so much!

We buy Underdays regularly, so we like them.
We like it is local brand, vegan, very quality material, we have a lot fo your underwears :), so you have to know we love your brand.
Do you think also sell brallets and again pyjama sets?

Really love Underdays. Their workout tops are so comfy and soft, they’re my favourite to work out in!

My wife loves these! She has tried a bunch of other brands, and she is so happy with Underdays. She loves the fabric, the fit, and the fact they are much more breathable than others helps. She also loves her tank! All around the best in her opinion, I have bought just about everything for her from Underdays.

Found the brand on Instagram and brought one as a try. Honestly, they are so soft and comfortable, it really does feel like I'm wearing second skin. The fabric doesn't shrink and lasts a lot longer than my other underwear. Since then I've brought 7 more pairs and haven't been disappointed. The colours are gorgeous. I'm waiting until my freelance gig goes permanent, and then I'll switch out my current underwear for Underdays.

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.
