There are sooo many ways to refashion a men's shirt (refer to my shirt dress post here) and this one, turning a shirt into a skirt, is a pretty easy DIY. All you need to do is cut the shirt, then add some elastic to create a paper bag waist (you could even do a little hand sewing job of the waistline if you dont have a sewing machine - doubling it over and hand stitching and threading through some elastic). I always find lovely mens shirts in thrift shops that are too big to wear so this is a great way to use them. Monoxious also has a great DIY on this aswell, where she leaves on the sleeves to create waisted ties for the skirt.
