Snug but still comfortable

Yes, I recommend this

Even though i had no idea if my new jeans would fit i just relied on M&S fabulous sizing and it was perfect. My new jeans fit snuggly but not at all tight. Im a member of a 300 strong choir and if we sing outside we wear jeans but they mudt not restrict my breathing and these certainly don't. Well done M&S

Sizing has changed and no it's not me!

No, I don't recommend this

I ordered my usual size but the jeans were far too small. Which is odd, since all my old pairs fit just fine. I ordered the next size up, which does fit. This is clearly an M&S thing, since trousers from other shops in my usual size also fit just the same. This is very irritating and time wasting for your customers.

Haven’t actually worn yet although they appear to be what I was looking for. A pair of jeans not too tight or baggy. I am between a 10/12/ and bought 12 regular perfect length for me 5ft 5”

Flattering, comfy and reasonably priced

Yes, I recommend this

I am really happy with these jeans. I wanted some ankle length jeans for summer and got them in the extra short length. I am around 166cm tall and these come just above my ankle bone - the short looked like I had just bought jeans a little too short - not a good look! They are comfy, flattering and a bargain. I'll probably get some regular length ones for winter. Run, don't walk to M&S for your next favourite jeans.

I was really pleased with these lighter colour Sienna jeans so bought a dark pair which were SO uncomfortable- so be aware different colours can be a different fit

Great jeans, stretch style and long length.

Yes, I recommend this

Perfect pair of jeans for me, ive not bought any jeans for at least 15 years and recently threw out 1 pair as they had worn in a certain area, looked around numerous places for jeans and just couldnt find any for me, i then thought of M&S and sure enough i found them, glad i took the chance & bought 2 pairs, very pleased and they are long length to fit my 5ft 11in height, very pleased.
