How to boost roblox res on shirts

I want to make decent shirts on roblox but the template res is too low

and it makes all the shirts blurry

if I change the res to be higher, this happens


Well, roblox only allows 585x590

How do people have high res clothing then? I see a lot of clothing be high res

They just make the most of the space they have in the template. At the end of the day, it’s all about formatting.
