add details and ill change my answer, we dont kno wat color skin u r, or hair, or anything, if u wear make up, if ur a guy or a girl, i was guessing girl cuz u said spa day. but add details and i will definetly try to help you, my best advice for right now is just to be yourself
my new changed answer:
you sound like your extremely pretty and probably hot. maybe you should try your natural hair color and see if it looks even better than your hair now, idk how long your hair is, but it would be totally awesome, (in the color that it is) with a hair cut, an inch past your shoulders, have some awesome layers, but make sure u can still put it up in a high pony tail., have some side bangs!!!
for hairstyles for it, put it up in a messy bun, (if you need some directions email me!!!) put it up in a cute pony tail some days, and leave it down other days with a cute head band, maybe a red one with white polka-dots. it would look real gud on your hear, bright colors look great with your color of hair.
for make up wear a thin line of eyeliner on the bottom, u dont hav to do the top if you dont feel like it. wear a ligt color of eyeshadow with some shimmer during the day, and if your going out with your friends to a dance at night, or the movies or a party at night, wear a little brown or black, but make it look smokey, not goth.
brown mascara wil be great for your eyelashes.
try some cute preppy clothes out.
like abercrombie and fitch
wet seal
hollister and stuff dats cute
short shorts and jean mini skirst look awesome with a tan and your hair.
dont just buy something cuz its 'in'. make sure it looks gud first!!!
for the spa, first get a massage so ur relaxed. then, get a mani- pedi and a manicure. i dont know what else your spa has to offer, but email me if u want to know anything else! i would love to help you with watevr you need, and still
remember to be yourself!!!
