Hi! It's Merav from Baby Hobbes Design, writing because of the overwhelming love from last weeks' post about how I upgraded my daughter's camp t-shirt.
Since you asked for more details, I decided to write up a tutorial on how to turn an ordinary boxy kids' shirt into a curvy top with flutters. For this tutorial I am using a kid size Medium shirt along with the Tansy's Knit Pajamas dress pattern because I love the curved edges. If you don't already own it, get yourself a copy of Tansy's because this pattern is super duper versatile (top, short dress, long dress and shorts)! Otherwise, you can use any knit bodice pattern-just remember to extend it.
