Slimming Slipper

How can I look amazing in this outfit? makeup? hair?
i know the amazing part sounds a bit over the top, but i have to look good, as i’m probably meeting the guy i like there. I’m 14, 5′6″ slim, medium skin (somewhere between rihanna and nicole from pcd), longish black curly/wavy hair and dark brown eyes. I’m meeting my friends at about 3 pm outside.. (its bound to be very hot and humid).I was thinking of wearing this green(jade greenish), cap sleeved baby doll top and light blue jeans. probably with white slippers and a green scrunchie. if at all thin silver hoops. we cant dress up too much.. but i have to look really good in a subtle way.. no bold makeup or anything.. please help me..
it sounds nice, but wear discrete makeup, darken your eyes, and a gentle… and i mean gentle touch om foundation on the cheeks. big and wavy hair is always cool, so make it a bit messy.
about the clothing I would wear a casual dress, it always makes you standout.
