hi! ok, here's some guidelines I can give you on which style you may like.
Take these in consideration first:
1. How much is your budget?
2. Your size
3. Your personality
4. Lifestyle
5. How often will you wear a particular style
If I had tons of money, I would go for ALL of them lol. But I'm on a tight budget.
Also, some of these may not fit all sizes. Hime gyaru is one of them (not sure about the rest). I noticed that Hime Gyaru fashion is totally for the petite girls. It is difficult to pull off.
Personality, if you're bubbly then, go for a funner style like sweet lolita, gyaru, fairy kei.
Think about how you can get access to these clothing too. Not all of them are available online, most require shopping services.
