Claire,
I will first say, "I love that show"! Before I go any further, understand that this show is quite biased in the sense that the fashion portrayed is not your everyday fashion for the regular person. The first clue is the amount of money spent on a new wardrobe and how little is actually acquired. If everyone took that show for gospel, there would be plenty of women who would become insecure about their appearance.
With that said, if you are still insecure, find out what "real" women(women who don't have a fortune for clothes) are wearing by doing some research online. Google would be a good place to start. Try to develop a better sense of "self" and don't conform to the trends this show portrays. There are plenty of amazing fashions out there that don't require such an insane amount of money which will allow you to look just as good if not better. Also, look online for some discussions about the types of clothes to wear for your body type as well as some makeup tips for your specific skin tone, etc.
I would imagine, that you have nothing to worry about. I don't have pictures of course, but I would say that you have come this far by being you and you should continue being you. Congratulations on the award! Don't let it change who you are because you are beautiful.
