Is it possible to shop for clothing that isn't trendy or geared toward the older generations?

I’m 30, and in the last few years I’ve noticed that I’m really struggling to find stores that I like to buy clothing from. The current fashion trends really don’t do anything for me, I feel like I’ve stepped back into the 80s (and I also would be more than happy to pretend that the styles from that decade never existed in the first place, I certainly don’t want to wear them again.)
The popular cuts of clothing right now aren’t working for me, either. If I find something that isn’t lacy or neon, it still seems that tops right now are cut very wide and boxy, and bottoms are all cut slim and close to the legs. That’s fine, and all, but I happen to be tall and busty, with broad shoulders and a lot of leg, while I’m somewhat narrow through my hips and thighs, and the cut of most things in the store make me feel like a big square with skinny little legs. I don’t like it.

On the contrary, I know where to find less “trendy” items, but they all seem to be geared toward older women. I can’t seem to find a happy medium between neon Aztec print leggings and knitted sweaters with cardinals on them.

I can’t be the only one. Where do you shop?
