Replacing a few pairs of existing scruffy Sienna Straight Leg Jeans for some new ones. Favourite colour is Indigo Mix (very dark blue). Though as with black ones, must be mindful that the zip area has a tendency to go somewhat white, particularly assisted by a car seat belt! If you look at M&S site at the ones coloured "Dark Indigo", that IS how the Indigo Mix & the black will eventually go in the same area. Wash inside out to protect colour. Don't seem to shrink much, if at all. True to size (14) & length of 'short' perfect for me, I'm about 5'4". Note that the same size in black is definitely just a touch larger though, not really enough to matter (so I've kept them), but hope they don't slacken up a bit when I've worn them more than once. All in all, I'd recommend these jeans, which is why I've replaced like for like.

Poor sizing

Originally posted on marksandspencer.com (UK)

I would have given 1 star on sizing. I had to go up a size but the fit is still not right. I can do them up but they gape at the back and the rise is lower than mid rise. M&S sizing for jeans is now very poor. I am still wearing M&S jeans in a 14 short from a a few years ago that are a perfect fit. Now I need a 16 extra short. I have had to compromise on the style because I have been waiting for months for the extra short in my preferred high rise style to be back in stock. I have now run out of patience so will vote with my feet and look for jeans elsewhere from now on. It’s a shame because I have been buying M&S jeans for years.

Disappointed

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

I had already ordered the same pair of jeans last year and really like them, so when I wanted to buy a new pair, I ordered exactly the same pair again, using the name and the reference number. I tried them on when they arrived and, apart from them being a bit long despite saying Short (I'm 5ft 4"), I was pleased with them and washed them. After I had shortened them, I wore them and was unhappy to see how baggy they became after only two wears. The other jeans I bought last year, don't do this. Perhaps you've changed where you source the material?

Originally posted on marksandspencer.com (UK)

I was very disappointed that they had the creases at the front put in to make them look worn. I didn't want that and should have sent them back but they fitted well and i needed them. Won't buy M&S jeans on line again. A pity.
