My clothes are not cool?
haha! dudeee i <3 Target!!!!!!!! If you shop in the juniors section you can find some really cute stuff :) hmm... maybe you can try marshalls (they have discount designer stuff so u can impress ur friends!), pacsun, old navy, forever 21, H&M, ross, aeropostale, abercrombie kids, etc! Also about the tie dye shirts... As long as you like it, it doesn't matter!!!! Adults are teenage fashion wannabees so ur most likely gonna see them wearing stuff you have- not matter where you shop! hahah my MOM has a shirt that I have. Don't worry! also, maybe pick up a fashion magazine like teen vogue, or seventeen just to get some inspiration on whats in style right now.
A good thing to do if you want good fashion is to start off with the basics. Get a pair of denim shorts, white shorts and jeans. Buy a few plain tops in different colors. Then shop for accessories so you can take the plain outfit and make it amazing! Buy necklaces, hats, bracelets, belts, hats, etc! Thats how i dress myself! I start out basic, and add sweaters and accessories to make it more stylish!
Also, some trends right now are studs, ruffles, floral patterns, stripes, button up shirts, tshirts tucked into skirts, summery dresses, bold accesories, and bright patterns.!
I hope this helped :)
