Clothing ...fashion...help?

I need a fashionista's advice. All the clothes at my old favorite stores are starting to look boring. I wear plus size clothes but I am slowly trimming down. So I need stores that can cater to that and have me looking great. I dont like preppy stores like holister and american eagle. My style is chic,boho on someday, somedays i like to wear a fashionable geek thing and New York street fashion on othe days. And I also like shopping at affordable boutiques.
