Vintage-style bell-bottom jeans and psychedelic prints

I'm starting to become more interested in clothing that is vintage inspired - like bell-bottom jeans and anything with a psychedelic kind of print. What has been most surprising is how difficult it is to find those brands that nail the older 70s inspired styles, without appearing cheesy/dated or way to modern. A lot of styles look great in the pictures but when I look at 'real customer images' or reviews sometimes the fit and fabric looks entirely different. I've been comparing styles, colours and price points between browsing various online shops, reselling apps, and marketplaces like Alibaba. There are a lot of brands bringing the flare back into the mainstream in a fresh way but the styles are all over the place, from more comfortable fit than regular jeans to streetwear coolness to really vintage looking. The psycadelic prints work just as well, from more chilled out to all out neon, and using actual vintage stickers as inspiration. If you're someone who already buys this kind of style regularly which brands do you think are doing it well in fit quality authentic vintage inspiration?
