Size discrepancies in 14 extra long sienna jeans

Purchased 3 pairs of sienna jeans 14 extra long like the ones I always wear. The light and mixed denim fitted perfectly but have now tried 2 pairs of the dark demim which are far too tight on waist and legs so must be a size 12 or smaller!. Very disappointing for M and S quality

The Sienna Straight leg jeans

Yes, I recommend this

Good quality jeans. The only problem was that they were too long. I ordered extra short, I usually order short, but have to turn them up, but extra short are still too long.

Disappointing

No, I don't recommend this

I bought 3 pairs in different colours as I wanted something comfortable to use for everyday, and these fitted well when I tried them on. Unfortunately, the first pair I wore stretched so much I spent the day hitching them up and they just look baggy and shapeless. The other 2 pairs were returned.
