Looking for some high quality, nerd ass gym clothes. Help!

Title. I'm looking for high quality tank tops and shorts that will hold up in the wash. I like nerd shit--anime, fantasy vibes, DnD.

I want to steer clear of Redbubble and Etsy unless people can vouch for quality. I'm tired of ordering something and finding out the print is an iron-on that will flake during washing.

A design I like from the Wizard of Barge: link

Here's the kind of tank I'm looking for--design is dyed onto the fabric. Sadly this was a random shirt I found at GameStop, and I haven't been able to find anything comparable. link
