Not the best fit for me,

I thought these jeans were petite - the length wasn’t too bad but they were quite baggy ,

Wow Perfect Length

Yes, I recommend this

Needed a dark pair of jeans but all stores I visited only had 12 short. Ordered extra short online, available to collect next day. They fit perfectly and are so comfortable to wear.

M&S jeans sizing is wrong.

No, I don't recommend this

Nice quality, colour and a fair price BUT the size 12 has a very small waist compared to other makes. I know a lot of people who have said the same with the other sizes as well and even the staff in the shop agree.

I can't buy jeans anywhere else! These fit fantastically and I love them. They wear really well and are most definitely worth the money.

I love these jeans; how they look, feel, fit. Everything is right about them. When I need new jeans when old ones have worn out, I come back to these again and again.

Wrong length jeans

I already have these jeans in a short length and I ordered these as extra short. However they were exactly the same length as my previous jeans. I was disappointed.

Nice straight leg, good fit, good denim. Thank goodness you still do these, have worn them for years and was delighted to still find them after searching through all the horrendous wide leg, funny shaped 'hoover bags' on display.
