Re-purposed t-shirts and clothes are all the rage these days. This very cool top from Lucky 13 Clothing / Felon Clothing has been re-purposed as a super sexy tube top! It has a screen print of pistols and the words "Love 'em, Leave 'em" across the front. The sides are knotted and fixed with safety pins. The bustline also features safety pins.
