1. Start purchasing dresses Hime gyaru is about a sweet and innocent princess appearance. If you already have cute, frilly dresses, that's a good starting point. Dresses are mostly knee-length, but some are shorter. Popular things on hime gyaru dresses are fake fur, pearls, animal print, flowers, bows and anything that's cute and sweet. But keep all these things in moderation, like ruffles just at the bottom of a dress, or lace on the sleeves. Don't make yourself look like your outfit it's eating you alive! Dressed tend to be very regal looking, and generally are in pastel colors-- after all, you're a princesss girl! Some popular brands are Jesus Diamante and Liz Lisa.
4. Get a hair accessory. One huge flower (i.e. a rose) or a silk bow are good hair accessories. If you don't have a bow a little crown or tiara (it shouldn't be too big or it will look funny), whether plastic or metal, will be an adorable option. You MUST have a hair accessory. Popular hairstyles include having your hair teased into a high beehive or boufant hairstyle, with lots of curls, or having a nice, simple bun. Straightened hair isn't very hime unless you have a boufant to accompany it--the elaborate big-hair hairdo is a trademark hime gyaru style. The hime haircut is perfect for hime gyaru--it's basically long bangs cut to your jaw, with regular bangs as well, the rest of the hair is cut evenly at one length.
5. Get some type of nails. Fake nails are very pretty, especially they are nice if you naturally have short nails, but if you want to go totally natural, a clear or shimmery white nail coating can be used. They should be decorated/painted in some fashion. Many tutorials for hime gyaru nails are available online.
6. Hime Gals aren't usually snobby! Be kind to others, and don't dumb yourself down to seem like a perfect princess!! And you don't always have to be frilly and girly, you can still do anything you want, gyaru is simply a fashion, it doesn't restrict what music you listen to, activites you do in your spare time, or how you choose to act. Lastly, BE CONFIDENT!! Lovely makeup, cute hair and nice clothes mean nothing if you don't think you look good
