I need help with an arrietty costume.

[Miharu1775]

I am wanting to take my sister and I to our first convention this coming spring and she and I both want to cosplay but it all depends on how much money we have saved up by then. I had wanted to go a kikyo from inuyasha but then I thought it might be a little cheaper to go as arrietty from the Borrowers. A friend said she can teach me to sew to make the dress and the belt but I am worried about the bag and the hairclip. If anyone can give me some tips about the construction of these items, I would thank you very much.
