Nice fit, I've bought these before in short leg, i was a bit worried that they are now labeled petite and they may be short in the body. They aren't.

Small sizing!

No, I don't recommend this

Bought to replace a smaller size. Tried on a pair size 16 in store before ordering online. Took on holiday and find they are no bigger than existing size 14. Have you changed sizing or different manufacturers? Either way very disappointing!

Great value for money

Yes, I recommend this

First time I have bought this style (sienna). Soft fabric and nice mid blue colour. Had to take up slightly as the short size 8 was longer in leg length than other M&S jeans I have bought. Good fit on me otherwise.

Nice jeans

Yes, I recommend this

Bought these jeans as they are available in different leg lengths. I bought size 14 short and just right for me at 5ft 1ins. Not the cheapest jeans and not worn yet so not sure if they will keep their shape but they are adequate for what I wanted, a pair of dark blue straight leg jeans.

comfortable jeans

Yes, I recommend this

I gave these jeans 5 stars as they are so comfortable to wear and wash well without any shrinkage. They don't flatten my stomach as much as I'd like due to the bulky zip area, not the cake lol.
