Sent a used pair of underwear in my first order. Sent a picture of the opened packaging, hair on the pants & lifting protective film, and they won't send a replacement ? Next to little apology. My first & last experience of the underdays. All you had to do was send a replacement single pair of pants, but no, refused. Very poor customer service.

Hi Heather,

Thank you for taking the time to leave a review, and we're so sorry this was your first experience with us. Receiving an item in that condition is unacceptable, and we fully understand your frustration.

We can confirm that our customer service team has since been in touch and arranged a replacement for you. We hope this goes some way to making things right, and that you'll give Underdays another chance.

Best, The Underdays Team

I love Underdays

I love Undersays! I workout 6 days a week and don’t wear anything else since finding these. They stay in place, no riding up or falling down- they are light, comfortable and super cute!

Still no refund

The workout thong was really dissapointing, drop front which means there's no support across the lower tummy area which is nice to have when working out. I ordered two different colours but only needed to try the one pair to decide they wernt for me. I parceled them back up & returned them the same day, that was 17th March, to date I have still not received my refund. I've returned items to Cider & Shein since then & had my refunds long ago! Not ideal.

Slipping is a problem

Lovely material and good fit .
Only problem is there is not enough material to cover bum cheeks and you end up pulling them down from bunching into your bum .
I’m a slim size 10 so don’t have a big butt to cover and still they slip .

Hi Ali,

Thanks for taking the time to leave this — and glad the fabric and fit worked for you overall.

Fit and coverage can feel quite personal, especially with lighter styles. Ours are designed to sit smoothly without digging in, but we understand that for some, that can mean less hold through the back.

We’d recommend trying one of our fuller coverage options such as the Everyday Brief.

I was looking for a new brand of underwear when I found underdays…I now have switched over to this brand. Very comfortable, light, cool feeling. I particularly like the editions with contrast stitching and will buy more pairs when the next set comes out. Service is quick. My only comment would be to reduce packaging.

Workout thong is Daylight Robbery. Don’t waste your money.

Bought the workout thong that promised no camel toe for running under leggings. I am a size 10 but bought the medium to ensure a good fit. Completely unfit for purpose. It is a thin, skimpy, narrow, flimsy scrap of material with fancy stitching that does does not offer adequate cover, let alone stay in place even when walking. Save your £18 and don’t be robbed like I was. The company only offers an £8 discount on another ridiculously overpriced product.

Hi Heather,

Thanks for sharing this, we’re very sorry it didn’t work for you.

The Workout Thong is designed to stay minimal under leggings, but it should still feel secure and stay in place. What you’ve described isn’t the experience we want.

Fit can make a big difference here, especially with movement. If you're open to it, we’d like to help find the right size or style for you.

Drop us a message at team@theunderdays.com and we’ll take care of it.

Couldn’t recommend Underdays more!

I’ve now converted my entire underwear drawer to Underdays, once I tried them there was no going back. The material is unmatched, the fit is great and I’m always looking out for new collections and colours. I couldn’t recommend them more!

90% of my underwear is now Underdays

90% of my underwear is now Underdays. I originally gave it a try after seeing it on Instagram. I then found I always gravitated towards wearing them because they are very comfortable.

Delivery is always fast and I like that each pair come individually wrapped which feels like tiny presents for yourself.

The range of colours keeps me repurchasing. My only tiny issue is the stitching on the workout thongs isn’t as high quality as the others for the price, but this doesn’t affect their wear.

Not worth the pennies!

I thought these looked great in the advert. I was looking for soft, comfortable thongs for the gym and that couldn't be seen through the leggings.
They are not comfortable. The 'under' area is so thin and the seams are not nice which rides in! The material is lovely and you can't see them through the leggings but I could've got that from M&S. Not exactly WOW! Not worth the big price tag!

Hi Sophie,

Thanks for taking the time to share this.

You’re right to expect both comfort and coverage, especially for training. The Workout Thong is designed to stay invisible under leggings, but it should still feel secure and comfortable through movement. What you’ve described isn’t the experience we want.

We’d like to sort this properly for you. If you email us at team@theunderdays.com, we can look at sizing or alternative styles.

Bought this underwear for the first time a few months ago and now I just want to get more. It truly feels like I am not wearing anything, they are breathable, comfortable... I didn't wear thongs before and I love them now.
The colours are fun and they fit perfect. I am sold.
I wish you did matching bras.

Will never buy from anywhere else

I love this brand. Such good quality material and super soft. Almost like you’re not wearing anything! It would be awesome if the brand did matching bras or little tops (like they do the workout set).
