Paige from Pink Lemonade and Simply Handmade by Paige shows how to make this lovely Anthropologie-inspired t-shirt. She starts with a plain black tee and adds gathered chiffon to the neckline. She got her gathered chiffon from a thrifted shirt, but you could easily make some from a bit of chiffon yardage. Go to the tutorial.
