I wanted to make my costume, and I wanted it to be as accurate as possible. (Most of the store-bought Tinkerbells you see don't really look like Tinkerbell - the dresses are often very elaborate, when Tinks is really simple.)
With a friend as Peter Pan:

I made the dress with out any sort of pattern. There are a lot of mistakes. It also came out a lot shorter than I had planned, which was entirely unintentional. (Although I guess that is accurate...)
For the wings, I used some wire my Dad had in his workshop and some cheesecloth my Mom had. I kept the cheesecloth in place by stitching around the wire and using tape.
I knit the slippers, using this pattern: http://www.purlbee.com/mary-jane-slippers/ I then added some pompoms I made.
With a friend as Hermione:

You can't see it in the pictures, but I also had a green ribbon tied around my hair (which was in a bun). Also - I did have wings on both sides. You can only see half in these pictures, from the way I'm standing.
Anyway, despite some mistakes, I loved this costume and was really proud of it. And it didn't cost too much, either - around $20 - I don't remember exactly how much the fabric cost, but the yarn (Patons Classic Wool) was relatively cheap, and I found everything else at home.

























Hopefully I'll be posting the finished product soon.
