Underdays Reviews 104

I bought some of the underdays for my daughter after seeing your ad on instagram. She did laugh, but…. Once she’d tried them, loved how comfy they were and I now buy for both my daughters!!

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.

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.

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, 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.

I started buying underdays underwear a few years ago. Yes, they are pricey to say the least but the quality is exceptional. It’s the softest underwear I have ever tried. It’s so comfortable for everyday wear. They sell out of some sizes quite quickly but that doesn’t bother me too much. They have a variety of underwear to choose from. I only purchase the thongs and I love the quality so much that I will continue to repurchase. The fit of the thongs are true to size. I’m a size UK6 and purchase the XS. I’ve thrown out all of my cheap thongs and replaced them with underdays underwear.
Communication has been great every time I have emailed their customer service team. Overall I would recommend this brand to everyone.

I love these pants!!! Can’t wear anything else now. True to size. Comfy. Sustainable. Great comms and service. Fast delivery (I live in the middle of nowhere).
I don’t think they should go in the tumble dryer, will be more cautious with that in future.

Amazing underwear!!!! I can’t praise them enough. Incredibly comfortable, soft and best of all, they have done wonders for me. Restored my confidence!!!!!!! Worth every single penny.

Order was not received, and no news from their team. Very disappointing.

The best undies ever!! I’ve made two orders from Under Days in a month and I can’t rate them highly enough. Well worth paying the extra penny and shipping to Australia

The quality of the items has dropped significantly. I’ve bought your panties many times before, and all my previous purchases were amazing. But this time, they started to pill after the first machine wash, and the elastic became warped. I’m really disappointed and not planning to buy more. This is especially frustrating because I truly loved your products before and had been a loyal customer for several years.

Super comfortable and high quality. Purchased twice, 5 pairs and then 3. Hoping eventually replace my all underwear with Underdays.

Can’t give a rating because I still haven’t received my order which was made 7 days ago. Package seems to be lost and I have no update of where it is or when to expect it

This underwear kept appearing on my Facebook feed so I decided to place an impulse order. I opted for 3 pairs in neutral/pale colours. Lovely fabric, nice fit and fast despatch.
I would have given 5 stars if it wasn’t for the cost. I do think they are a tad expensive. I would recommend them but only if money isn’t an issue to you.

One wash and the logo and printing washes off.

Underwear is expensive for what it is tbh. I’m also convinced they consistently have the tiniest bit of stock for sizes XL and XXL as they are always out of stock for every pair and colour. Even if I shop right on when a new colour drops, it’s still out of stock. Clearly they don’t care about all customers. Unsubscribing and won’t be returning.

Purchased for my GF, she's loving her UD set!

Very poor timings processing refunds of items that have not been opened and returned in a timely manner.
Dear Team underdays, any news on my return please?
This is also part of a timely customer service.
I have purchased items before and have not used returns. However I am disappointed regarding your timings to processing returns. Especially as the items had not even been opened or taken out of their envelopes.
I hope you will resolve my refund request in a timely manner.

Best Wishes,

Marilena
