I have wanted to throw together this costume ever since I first saw the show. If you don't know who Winry is or what FullMetal Alchemist is, I strongly suggest you watch it. It is amazing and if you don't like subtitles, it has great dubbing with great voice actors.
Back to the costume. This is one of the outfits she is seen in casually. She also has a jumpsuit outfit that is cool, but I don't own a purple jumpsuit.
The outfit is easy, if you have the pieces, the only thing I spent time on was recreating her hair.
(I was trying to imitate a pose I saw her in, but it is hard to flex with a crescent wrench in your hand)

Gather together the clothes you will need.
White Tank (I used a white beater with a white simple tank under)
