Pinkie Pie Cosplay Help

[fluttergirl 9]

So I really would like some cosplaying advice, especially from some female forum users...

My boyfriend and I are going to BronyCon this summer, and I have an idea for a Pinkie Pie cosplay, but I need some help getting a "final draft" of it. I wanted to go out as a "punk rock Pinkie Pie", but I have no clue where to kinda start. I've never cosplayed before, and this will be my first convention, so I want it to look really good. Any suggestions/tips?

Thanks in advance!

I have never cosplayed in my life either (although I want my first cosplay to be L from Death Note. >w<).
I would suggest...first, finding some Pinkie Pie attire! Like you can go to Ebay, Amazon...or if you feel creative, you can make a costume yourself and wear all pink. Simplicity is always good.

After you dress like Pinkie, alter your look!
Make yourself look punkish. Ya know, maybe if you wear pink punky lolita clothing, that can work! I happen to notice that Pinkie's special event attire looks very lolita. :3
