*To accessorize with the girly style add a cute pastel color clutch, a hairband (with a cute dainty flower or a feather), and stacked bracelets. With this look wear light, pastel colors! If you add darker, brighter, or bolder colors you wouldn't look like you're trying to achieve a girly look. The girly look is all about light colors and being dainty and cute.
*For the edgy look wear your hair up in a messy ponytail. Chose to wear some studded/edgy looking jewelry and an over sized black leather tote bag. For the edgy look wear blacks and grays.
*Last but not least, with your preppy look add a layered pearl necklace, a solid black clutch, and a cute sassy, girly watch, (Blair Waldorf from "Gossip Girl" is a good inspiration for the preppy look). Also with the preppy look the colors I suggest wearing are dark colors such as; dark blue, mustard, red, and dark purple! With a preppy look outerwear that is best to wear are blazers and cardigans.
