i found this gigantic men's shirt at goodwill for $1 (love the half off men's stuff for father's day sale!)
i cut down the sides, and the sleeves, trimmed off the collar, and added ruching up the sides. i cheated a bit though, i used elastic sewn inside to make it gather and then sewed on the ties.
i wanted a really long shirt. i wanted to keep the sleeves long because i have an unfortunate tattoo i need to get fixed soon on my arm and i'm self-conscious about it showing. it probobly would be cuter without sleeves, but maybe when i get it fixed i'll alter it some more. :)
EDIT: i think i decided to keep the long sleeves. plus that way i can wear it to work :)
