Remember to design clothing for whatever culture you’re developing. What kind of fabrics or styles are common? What colours- swamp people are’t going to wear pastels and desert folks won’t wear black. How about jewelry and makeup?
Keep in mind scenery, too! Just because two places are similar, doesn’t mean the clothes will be. A hot place without much sun is going to look a lot different in terms of clothes than a hot place with a lot of sun. People who live near an ocean dress different than people near a lake, and very different from people who live in a swamp.
Also! No matter how dramatic it is, people who live some place very windy aren’t going to wear a lot of loose, flowing fabric. Some, maybe, like a veil or a shawl, but not skirts and the like. Too many people would trip!
