Quality T shirt

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

Like others have said my T shirt had a horrible smell when it arrived. It was the brown one. I hung it up and it dissipated a bit after a few days but was ok after washing and it did not shrink. I’m normally 8-10 but got the 6 and it is still a nice boxy shape and length is fine for me. I’m 5’4”. It’s a good quality fabric and holds its shape well. I would have liked the little slits at the side hem like the white one I got last year but I’m happy with it anyway.

Very smelly!

This t shirt is not bright white but has a greyish tinge. It had such a strong smell when it arrived that I had to wash it straight away. This has happened before with cotton M and S t shirts.

Great quality T-shirt

Originally posted on marksandspencer.com (UK)

I bought this T-shirt as I liked the boxy style and the thin stripe. It looks great with linen trousers for the summer. It’s also excellent quality, a nice thick cotton.

Looks good

This style is meant to be worn loose, but was still loose when I went down two sizes. Looks good. The striped T shirts look best.

Wouldn’t recommend the white colour

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

Bought this in white and sent it back, the white was an odd colour, like a grey/silver white - not a bright white, which I didn’t think was good as white goes grey after a few washes. I have it in brown and brown/white striped and they are lovely colours and excellent quality, I just found the white to be an odd colour

Gutted!

Originally posted on marksandspencer.com (UK)

Absolutely gutted. Love the shape, the material. Even my husband said it was lovely. Bought them in the multiple colours and 3 shrunk. I am not of a belly top persuasion. No probably at shop-returned and tried again. Shrunk a lot less. But still. Such a shame. Maybe I was just unlucky. Regardless, avoid the white. It’s the chewing gum shade of decade old undwear. The red and brown have been the best.

OK but not brilliant.

Originally posted on marksandspencer.com (UK)

Nice thick fabric, a bit too short. I bought them as I've got my arm in a cast and I need wide sleeves to go over it, they're ideal. Would have liked more colours to choose from as I ruled out the white ones having read the reviews and I don't like brown.

Happy with the T shirt - lovely fabric

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

The fabric is really comfortable next to the skin, I didn't realise the T shirt had dropped sleeves, I would have preferred a set in sleeve. Non the less because I like the fabric I will keep it.

Heavyweight boxy tshirt

Originally posted on marksandspencer.com (UK)

Lovely thick material,hangs well and looks good on. The only thing is I had to try 3sizes before I got the right one. I am usually a 14 but had to go down to a 10 and still roomy. But pleased I persevered.

Favourite top of the season

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

I love this top. The material is perfect for the changeable weather and hangs beautifully. It is just the right length to hide my tummy but not too long to make me look boxy. My favourite top at the moment.
