Calling all fashion able people!?

I'm going to a bbq tonight for a birthday party and I'm not sure what I should wear. I have everything you can imagine in my closet so that is not an issue. I'm also pretty sure that I'm going to arriving on my boyfriends Harley, so you must keep that in mind! But I will do some sacrificing in the name of fashion, as always. I'm 5'4 with a hour glass shape and I'm not quite tan yet but not pale either. I'm not sure if this matters but I also have brown hair and brown eyes,
