Here's Sandra from 5 inch and up in a genius lil diy skirt made from a button up shirt! No alterations involved, just a sneaky steal from her bf's closet. Must try!
I imagine you just slip the shirt up to your waist, (don’t do the top few buttons) and tie the sleeves in a knot… it sounds super easy in my head. Yet to see if the real life execution goes as smoothly.
