Cotton trousers / Lucy and Yak alternatives

[fortheloveofcheesecake]

Help me out Mumsnet! I love my Lucy and Yak dungarees and also loved the Alexa trousers for work but have had some issues with quality recently on both the dungarees and the trousers.
Can anyone suggest an alternative? I would like black, not tight fitting, elastic waist would be great but not essential, cotton not polyester etc is essential. I'm a 14/16, 5'8". I would wear them with a plain work t shirt.
I struggle with clothing and was happy in my Lucy and Yak bubble but need to find something else and I don't know where to start!
Thank you for any suggestions!

I've had some lovely ones from a previous recommendation for here www.clarenceandalabama.co.uk/collections/dungarees

M&S had some barrel legged trousers that looked a bit like Lucy and yak alexas. Navy. Can't remember the waist sitch.

I like my alexas but I find they rub a little on the thigh where the seam and my bulky thighs are. I would like a similar styled pair so lurking
