Start by getting your hair done/cut/restyled. Curl your lashes and use either mascara or eyeliner. Nothing heavy. Use lip gloss with a faint color to it. Buff and polish your nails. You can wear jeans but try a top that has a girly look (not necessarily floral either). These are small things you can try at home and if they make you feel more feminine maybe you'd like to up it and get a manicure, or buy new clothes, or try new makeup tips. Accessories help too. I like unusual bits of jewelry (nothing chunky). I usually wear hoop earrings and lipstick to dress up my ball-cap when I have little or no makeup and my hair is being difficult.
