Good basic t-shirt dress

Yes, I recommend this

Staple t-shirt dress which is useful casual wear in the hot weather. True to size but is quite long, I am 5’5’ and the regular length comes down to my ankle. Flattering split, overall very easy to wear and flattering as skims over curves.

This is a lovely, straightforward T shirt dress. It's well made, casual and looks good with a stylish necklace. And, it's reasonably priced. I like it!

Good quality

Originally posted on marksandspencer.com (UK)

A good quality t-shirt dress at a reasonable price. Arrived a bit crumpled, however. It's a decent weight, true to size and can be dressed up or down a bit. Only 4 stars because of the packaging and because its just a t-shirt dress, when all is said and done.

Bought to replace an old t shirt dress. I’m usually a size 14 but there were none in stock so I sized down and it fitted perfectly. Lovely styling, fit and cut. I love the slit.

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.

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.
