A quick internet search suggested a shaggy bob haircut/ asymmetrical bob, wavy. Or short with choppy bits on top for height.
V-neck or open collar shirt/blouse. Not sure what type of jewellery. Earrings are always good - maybe pretty
stud earrings? Main advice is not to worry about it - all the other people aren't perfect. Just go out and enjoy yourself. : ) PS Wear the colours that suit you best. That is the thing I notice first about people. Best wishes.
