Super easy project! Take a tanktop and an overized shirt, cut the tanktop where you want it to end on your body (waist level), cut the oversized shirt under the arms. Pair them together, flip inside out and sew the tank and shirt together. You might have to make little pleats in the shirt if it's bigger than your tank. Once you sew it together you're done! You can add an outer elastic or wear it with a belt like I will. Easy peasy!
