Oh how I heart a romper on a sweet baby boy. I purchased one at Target a few months ago and MC (seriously, go check out her sewing, you wont be disappointed. She is my little boy shirt sewing hero) said she knew of a pattern similar, Kwik Sew 3730. I was feeling up to sewing today, so that's what I did, not to mention if I don't get started soon baby boy will be all kinds of naked.
I used a lightweight shirting, it was quite slippery but it feels so nice.
The only (intentional) change I made was to line the yoke. I wanted to be able to attach my label and size tag, so I just cut two yokes and sandwiched the back piece in between. I like that it gave a nice clean finish on the inside and is a fun pop of color.
For the under collar I also cut it in a contrasting color. Little details make me happy.
So, the instructions kind of really were bad. And the inside facing was waaaay too long, so the insides are all kinds of ugly. It kind of made me sad. I didn't bother hand stitching the collar closed as the facings were messed up and I was just mad at that point. But now I know how to adjust the next one (that is already halfway done btw).
Technically this garment is a size small, but looking at the measurements it seemed to be about equivalent to the size 3month things I have sewn already, we shall see.
I chose to go with snaps instead of buttons, much easier for dressing a wee one, and those pockets kill me dead. Not like they are needed in any way, but they are adorbs.
