Underdays Avis 

Since I discovered Underdays, I can't buy any other underwear now. I immediately feel the difference vs other underwear! There is no itchiness, they are so so confortable and just feels good. I also recently bough their new bralettes, and for someone that really struggles to find a comfy one, this is the most conformable one I've ever wear, I'm in love with it! just waiting to have my size re-stock to get another one!

Love the underwear and reach for it more than other brands, but sadly the stitching came off with less than 2 month of using them. in strings the gusset is too narrow and not as comfy as cheeky and full briefs

I wouldn't buy any other underwear now! I have never felt comfier being in underwear all day. I love the colour options, and now with the bras as well. Honestly, Underdays are my only go-to for underwear now.

Easy to order and very quick delivery
I’m hoping that more colours are coming?

Looks great, feels great, absolutely LOVE the bras and thongs in this line. I have every color, and binned all the others I used to own…they are as good as they look!

Most comfortable knickers I own, I always reach for these, soon as they are out of the wash, they’re on! They stay soft forever, no cutting in to you and super flattering fit. I have the thong, everyday brief and everyday cheeky

The underwear is comfortable, washes well and wears like a second skin. They are good quality material, but are pricey. Look for coupons or buy on their sales. They run out of color choices and sizes quickly. Shipping is not the fastest. Restock is slow.

I ordered two pairs, one workout thong and one everyday cheeky. While both looked nice, I immediately did not like the thong as the private parts area is very narrow; I did not even try them on. The everyday cheeky was better, even though the private parts area could be wider. All in all, I like the material, but I'm disappointed in the "functionality" of the knickers for women. I'm therefore still on the lookout for THE knickers..

My absolute favourites!! Customer service are also great and the quality is 10/10

Great products, really high quality and well-considered. I'm an Underdays convert, and so are my friends and family! Never had any issues with orders or delivery.

Underdays products are as promised, comfortable and of good quality. I hesitated at first as I have been disappointed with previous brands. However Underdays did not. They are competitively priced and have frequent and good sales. I am happy with my purchase.

My sister and I are obsessed with underdays. Just the best!

While this is a really nice concept and INITIALLY the underwear is lovely, I have found that after less than a year there are already holes in the underwear and they’re not washing very well. The branding fades almost immediately - while this isn’t necessarily an issue for me it just highlights the lack of quality. I really wanted to love these but for so many reasons they just don’t cut the mustard. I have also found that the stock is such a big issue with the larger sizes. I used to check religiously for when they would restock the XL size but it was so rare and when it did restock it sold out almost instantly. I did email about this but I remember even at the time they weren’t able to provide much of an update about when larger sizes would restock. Aside from this the quality is a major issue and I feel I have given them a good few chances by trying the different colours and styles. The are comfy but to me when they are breaking and becoming thin after only 6-12 months of wear (sometimes even sooner in some cases) they are not worth the premium price tag. I was sad because I liked the concept and initially the look and feel but the quality seems to be majorly lacking. Under the consumer rights act 2015 a product must be of ‘satisfactory quality’ and ‘durable’ meaning it should last for a reasonable amount of time. The time these products have lasted certainly is not reasonable and I would not consider them durable with, to be honest, less than even normal use.

they are so soft, so breathable, so comfy, amazing for everyday
truly shocked that underwear was able to be this comfortable and look good at the same time

My go to knickers! Their knickers are the most flattering and oh so soft. I’ve gradually upgraded all my underwear to this brand.

Great soft material

Love this underwear. It’s so comfortable and great quality. I’ve just bought the bras to match and they fit perfectly. Would recommend as they are my go to underwear

Bought these for my wife. She has replaced most of her underwear with underdays.

Weren't the right fit for me, the pubic triangle of the underwear was really narrow so had to return most of the underwear. They were really soft though!

EDIT: The company has been in touch to try to rectify things. I have changed my review.

The item I received is nice but the overall experience was disappointing.

Ordered 2 bras, one black, one white. I got a dispatch email quite quickly, but over a week passed and I’d had no further updates on the progress of the parcel. Checked the tracking and it hadn’t moved – just said Royal Mail were “expecting” the parcel.

Got in touch with customer service, who said the order had been lost and offered to re-ship. I gratefully agreed to this, only for them to come back and say the white bra was out of stock. Asked when it would restock, and they said October.

I now suspect that when I made my original order, they didn’t have the white bra in stock all along but they processed it anyway.

I’ve received the black bra and it’s nice but I only got half of what I originally ordered. It’s such a shame because I like the product.
