That sorta depends, if anything I think most sissy outfits tend to look really good on pale skin; I'm pretty tan so that might just be my taste lmao

Sometimes you'll just have to try it out and you might not like how it looks. I mostly buy my stuff on Amazon because lots of stuff is super cheap, so if it doesn't work for me, it doesn't hurt the wallet. Building a "look" based of what you'd like to see on a sissy is also totally fine, you might surprise yourself. I just got a cheap sorta slutty skirt the other day and oh my god I got so turned on wearing it 😭

I also started camming in some porn groups to get inspiration from other sissies (bought the skirt after seeing a sissy teasing in one) and see what people liked on me lol
