cute but thin fabric

It's a cute style, but thin fabric. M&S do a lot of lovely tee shirt material. Not sure why this one is so thin.

Brilliant dress for holiday and warm days here. Roomy. Comfortable. Light. Splits at the side give it a bit of style too. My 2nd one.

Great dress

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!

Originally posted on marksandspencer.com (UK)

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.
