I love this dress!
I made it last night, loosely based on the fantastic t-shirt dresses at Lil Blue Boo.
It started as the remains of a onesie I used for this project.
1) To make one yourself, start out with a t-shirt or onesie, and add some length by cutting out a section of another t-shirt (or other jersey fabric) in an "A" shape, slightly wider than the bottom of your shirt at the top, and gradually larger toward the bottom.
2) Then sew up the sides of your "A" piece, and pin (right sides together) to the bottom of your shirt.
3) Cut out lots of small rectangles in the colors of your choice. I chose a teal, light pink, and bright red, and my rectangles were about 2"X1", and pin them to your dress in a scarf pattern.
4) Sew rectangle pieces to your dress. (You'll probably have to shift them about a little as you sew, so this part can be a tiny bit tricky.) Snip the edges of the last pieces to make a scarfey-looking fray!
5) Then cut to long strips for your bottom ruffles. You'll want them about twice the length of the bottom of the dress, and one strip about times and a half wider than the other. For example, my dress bottom was 22", so I cut a 3"X44" strip in pink, and 2"X44" in red.
6) Use your longest strait stitch to sew all the way down one side of each strip, and pull the top thread to ruffle until it is the length of the bottom of your dress. Sew the open edges of each ruffled strip together, so that they are circles.
7) Lay the 2" wide strip on top of the 3" wide strip, then place them, face down, onto the bottom of your dress and sew on.
