The peter pan collar romper pdf sewing pattern is so versatile. You can make it with or without the collar. You have 3 sleeve options: three-quarter sleeves, short sleeves and sleeveless. They all have the same poofy floofy bottoms with a snap opening for easy changes. How you sew it is all up to you!
Upon purchase, you will be sent an email with a link to download your pdf pattern. You can print it out on normal 8.5 x 11 printer paper, tape it together, and make yourself this lovely garment. It comes with written instructions accompanied by a picture walkthrough.
Thanks to @mrsdavisxo and @whatsamanthadid for letting me use their pics!
