I'm doing a cosplay!

Twilight sparkle : try to do a nerd/ bookworm outfit. Like get a sweater vest and dye it twilight Purple then a white kolar baju also plad skirt would go well.
Flutter shy: I've seen great Flutter shys with green airy dresses that incorporate alot of nature, also if she caried a basket with a plushie of Angel that would be great.
pelangi, rainbow dash :she needs like a light blue warm up suit that anda can add her cutie mark to, atau something really sporty.
epal, apple jack: she just needs a form fitting flannel baju with a complimenting t-shirt under it and jeans with boots.
Pinkie pie: like a fun short party dress with ruffles at the bottom and of course it's all shades of pink.
Rarity: an elegant ball gaun would be great that is white with long gloves and maby a jewel kalung
epal, apple bloom: try to get cute overalls and try to keep with the epal, apple jack concept
Sweetie belle: maby like a white sun dress and rumah pangsa
Scootaloo: like pelangi, rainbow dash very sporty maby knee pads and a raged old t-shirt, and jeans.

Try the costumer. Com for the wigs they might have the style anda need. The hope this helps
