I'd like some advice for designer who does vintage designs

1900-1990s is my goal really
i love the diversity and aesthetic of those decades
please let me know any tools or packs i need
and most of all tips
that'd help a lot

use serif fonts, minimalism is the key for 90s tbh

it further divides into brutalism vintage etc
for 80s go crazy on collages

I would use all the effects that came with the app CAPCUT. You have many 80s and 90s vibes in there

Your best bet is to build mood boards/idea boards based on what aesthetics you like from each decade and use that as inspiration to move forward with your designs. You can do this on Pinterest, Behance and other sites. You can even build your own physically if that works better for you.

Look at fonts used, colour schemes, patterns, textures, style of photos, etc to give you an idea of how to incorporate that look into your designs.
