Can someone help me find something similar to this photo but nicer quality?

I’m looking for a two (or three) piece co-ord trouser set. Something casual and relaxed looking like this Shein one but at under £18 no doubt that will be awful quality and the material looks hot and sticky.

I’m looking for a darker colour as I’m light skinned and don’t suit pale colours so black, navy, dark grey or something similar.

I want it to be comfy enough that I can wear around the house but will look equally stylish for popping out and I can wear with trainers but also flip flops/sandals.

Any suggestions, ideally not too pricey but happy to invest if it’s good quality and will last.

I’ve out this imagine into Google but it just comes up with similar colours and places like Shein and Temu.

I got a lovely one in Monsoon last year. Very surprised at the quality and cut.
It was in the beach wear department.

And I’ve just bought this set in brown.
