Please help me find navy trousers for work?

[WannaBeCool]

I am desperately searching for a couple of pairs of navy trousers. I need them to be in a size 18, cotton or cotton blend but no polyester or polyamide, not wide leg but not skinny and under £30.

I have ordered around 18 different pairs from various shops and only found 1 that is suitable but they are mostly linen so will get creased and not look great by the end of the day.

Does anyone have any suggestions? I've tried M&S, warehouse, Tesco, ASOS, la redoute.

I bought a pair of slim fit cotton/viscose blend ankle grazers from M&S. I’m a size 18 5ft 4 and the short length sits right on my ankle, the regular length are full length on me (I don’t like ankle length trousers so bought the regular). They have enough stretch to feel comfortable, not too tight through the leg and are perfect for me for work. I can’t get a link to work but they’re the £35 ones - there are similar for £25 but they’re a cotton/polyamide blend.
