I made the jumper from a long green stretchy cotton dress (freehand, mind you - they don't make patterns for long-legged jumpers) and a crab t-shirt my friend had made.
I cut and sewed the t-shirt into a half-shirt w/off-the-shoulder sleeves.
I dyed, glittered, and banded the hat - then put a circle of cardboard in it to make it stay flat.
I cut the wig and dyed the tips of the hair.
I also used makeup to make me look more Sri Lankan than Caucasian, but makeup is a completely different talent of mine. (Ignore the super-white-by-comparison upper arms... I wore a jacket all nite.)
The pink jacket in the last photo, I purchased based on M.I.A.'s signature "who cares if it matches" attitude and the shiny jacket she wears in the video for "Paper Planes"... This costume was so much fun!
There are two pics below are the real M.I.A. for reference...
And if you've never listened to her music - please do... it's amazing.
