Top: I recommend like in the picture, NOT the color black. I think they cause some weird reaction when you wear it in the sun like heat? Find just bright neon crop tops or just regular bright crop tops. Today, I wore a bright orange neon and grey crop top! (Thats just an example for you to wear but you can wear tank tops, regular shirts, ANY type of shirt style but the light and bright colors are the ones you're gonna look for!)
Bottom: Honestly, I don't recommend bright color jeans. I'm not gonna say it because it may offend some other people. BUT, what you could wear is bright color SKIRTS! But I guess you could wear bright color jeans if your not a skirt person. Usually they have these jeans at JcPenneys mostly for Juniors/Teens section.
Shoes: This is gonna be sort of the MAIN one because everyone looks at there shoes often. Like on my "How to get ther perfect shoes for back to school" post on the Accesory section I think, those are the TOP brands I'm looking for you to wear! Wear bright color converse, toms, flats, and others EXCEPT Uggs or shoes for winter. There has to be like a neon converse, light pink toms, bright blue color flats, and more! You can wear bright color high heels if you like! :)
Accesory/Outwear: NEVER wear bright color sunglasses, I think bright nerd glasses are the ones your looking for. Hats, jackets, earrings, etc. are good too with ANY bright color!
Thats all for bright colors, Have fun Shopping!
