Sienna Jeans perfect length at last!

At last I've found a pair of M&S jeans that are just the right length. Over the last few years every pair I've bought from M&S have been too long. Please, please don't making any changes. Unfortunately I could only get the indigo colour,now awaiting more colours to come into stock.

Good everyday jeans

Yes, I recommend this

I chose these jeans in Indigo with a long length, which are perfect for winter. They areslightly narrower in the leg than I was expecting. Good amount of stretch and will be a staple pair of jeans.

Jeans staple in my wardrobe!

Bought as an addition to my Jeans wardrobe. Already own a pair of Sienna Straight Leg jeans - now showing distinct signs of it’s popularity as a wardrobe staple. Also conscious that I have lost some weight, and could do with another pair. Is there a black Sienna on the horizon?

Good Value Comfortable Jeans

Yes, I recommend this

These jeans are great - very comfortable. However, I usually buy length ‘short/petite’ but they are longer than previous pairs I have purchased, so I had to return. I haven’t had much success purchasing my size in ‘extra short’ as they’re continually out of stock, so I’ll keep trying!

Amazing comfort

Yes, I recommend this

Been a fan of Sienna jeans for ages and these are amazing, good quality, reasonably priced - the colour is just as hoped, and although they seem a bit longer maybe I'm shrinking! They are so comfortable, I'll possibly get a different colour soon.

Disappointing

No, I don't recommend this

These jeans were baggy and unflattering compared to the Sienna straight jeans I bought last year. I feel that the sizing and shape has changed! I will be returning them
