Ok, I don't know what your budget is, and I'd need to hear your answer to Rachylou's question to give better recommendations. I have been into a full-on dystopian phase, but lately I've been leaning towards a sort of happy pastel color for warmer weather (shiney sky city) and neutrals for winter (a bit more dry/dusty dystopian feel without as much of the distressing as before.
Here's a general list of where I look for inspiration across the spectrum:
Helmut Lang
Rick Owens
Isabel Benenato
Barbara I Gongini
Damir Doma
Demobaza
Kowtow
Oak
Ovate
H&M divided
COS
Etsy shops:
Metamorphoza
Aakasha
Marcella Moda
Maria Queen Maria
AryaSense
Once you fall into that etsy rabbit hole, it throws similar designers at you in recommendations. I listed the ones I've been stalking the longest but my list is nowhere near comprehensive.
