I recently purchased my first ball jointed doll. Her face mold is ResinSoul Lu and her body is the standard 1/4 female body that comes with that face by default. I want to make her a sci-fi character, but I'm having trouble finding sewing patterns that fit well with that theme. There are a few things like hoodies or tights that could fit depending on what fabric is used, but I'm looking more for stuff that's specifically designed for sci-fi. I'm aiming for a pulpy retrofuturistic vibe but I'm not picky. I'm hoping for designs that specifically fit the ResinSoul 1/4 body but I'm not picky about that either as long as I don't need to make any major alterations.
Gracefaerie has some items that might work for you, if you pick the right fabrics (gracefaerie designs: Patterns Index), and patterns for Ellowyne Wilde should fit your girl with some reasonable accuracy. There's a fair bit of costumey stuff for Ellowyne if you go looking. Some other shops with more costumey pieces you can reimagine in different fabrics: Requiem Art Requiem Art Designs by DGRequiem on Etsy Racoon's Rags Raccoon's Rags by RaccoonsRags on Etsy Designs by Jude Designs by Jude by designsbyjude on Etsy
