Really pleased with the quality

Ordered a cardigan and blouse together and I'm very pleased with both. The cardigan has a nice weight to it and the blouse fits as expected. Everything arrived neatly packed after about a week.

Much better than expected

Bought two polos for work and they've quickly become favourites. The material feels good, the collars keep their shape after washing and the sizing was accurate. I'll probably order another colour.

Helpful customer service

I put the wrong postcode in by mistake and emailed straight away. They replied the same day and corrected it before dispatch. The jacket arrived a week later and fits beautifully.

Good overall experience

Ordered two shirts. One fits perfectly and the other is a little more relaxed than expected, but still wearable. Delivery was straightforward and tracking was easy to follow. Good value overall.

Looks more expensive than it was

Wore this dress out for dinner and had two people ask where it was from. The fabric falls really nicely and the neckline is neatly finished. It also looks very true to the website photos.

Found exactly what I needed

Was looking for something smart but not too dressy and found a blouse very quickly. The site was easy to use and it arrived looking exactly like the photos. Very happy with the fit.

Simple website and a good jumper

I'm not keen on spending ages shopping online, so I liked how simple the site was. The jumper arrived in about a week, feels soft and fits well. No complaints from me.

Lovely trousers, slightly generous sizing

These hang really nicely and are very comfortable around the waist. The fabric doesn't cling and still looks smart enough for work. I'd probably size down next time, but otherwise they're lovely.

Spot-on fit straight away

Ordered a navy shirt and lightweight jacket and both fitted properly straight away. I'm just over 6ft and the sleeve length was perfect. Tracking updated normally and the quality is very good.

Good jacket for the money

Really decent casual jacket and pretty much what I wanted. The fabric feels good and the zip seems sturdy. Sleeves are a touch longer than I'd normally wear, but I'm still very pleased with it.

Lovely dress, slightly slow delivery

The dress is beautiful and the colour looks just like the photos. Fit is flattering without being too tight. Delivery took around nine days, a little longer than hoped, but I'm very happy with it.
