You started babbling at the end there.
Anyway, look your best, you're fat but don't let that stop you from looking like a really good fat man instead of a really ugly fat man. If such a thing as a good looking fat man exists you will be him.

Wear something that makes you feel as good as possible! Go out and enjoy yourself. Be confident and have a great time. Weight is not everything, but if you want to lose it consider healthy eating and exercising for 3 hours or so per week.
