Excellent value for money, soft cotton, lovely fit, doesn’t cling to your body, received compliments from my 30 year old daughter who said it was very flattering on me and now she’s going to order one for herself.

Just what I wanted!

This dress is super. Good quality material, not thin. True to size. Very nice boxy shape on top. The only downside is that it is far too long but took it up myself. I’m 5’3”. Definitely a keeper.

Very comfortable material and good quality. Pretty basic but nice colour and works for everyday. I would recommend it if you're looking for a T-Shirt Dress.

Basic black T Shirt dress

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

The dress is just a long t shirt with a split to one side. The quality is average, after wearing and washing the seams wouldn't line up so it's a bit off centre. Its a generous fit and might benefit from a belt or cardigan or top to give it more shape. I kept it because I needed a black dress for a funeral and M and S failed to deliver to my current address so had to order something I could pick up in store. I might wear it for work in future.

Nice dress too long.

Originally posted on marksandspencer.com (UK)

Had to return as much too long. Very hard to get nice dresses like this for short people. I'm 5ft and it just looked silly. It's a shame as dress itself perfect for everyday wear. Very disappointed.

Bought this in black and love it. For chillier days looks good with a denim jacket. Sleeves not too short, relaxed fit, hangs nicely and like the side split
