I went by the dollar store the other day and saw these great men sheer beater. They came in black, white and gray, I bought one of each in a XXL, since they were only $1 anyhow.
I Simply placed two 6" ( $1.25 each) zipper diagonally onto the top and got my self and awesome shirt for less than $4 =]
I DIY my owe slashed denim as well, I took my old pair of black jean, which i has to turn into a skinny first ,then snip away and threw it into the washing machine. Voila! im happy with the result.
