I wanted to make Ansley a dress like my new favorite dress. Unfortunately I don't have a little cap sleeve shirt to trace for her. Fortunately I have a few shirts that aren't super flattering on me and that Tyrone doesn't wear.
Here's the first version. I traced a shirt with proper sleeves and tried to mimic one of my cap sleeved shirts. The shape was alright but it was a little big.
More pictures of the dress, b/c she's cute.
Here's the second version. I used the blue dress as a guide, taking in the sleeves at the armhole and the edge a bit. I like how it looks in some of these pictures but it looks tank toppy in other pictures (which is probably partially due to having never washed the brown shirt). Maybe it's b/c there isn't a defined cuff at the edge and/or the fit is a little off? I don't want to make them too much smaller b/c I don't want the dress to be difficult to get into.
Here are some sketches of how I made these:
Prewash your shirts! The sleeves on the brown dress were cuter before I shrank them. I'm not too sad b/c it was a practice run anyway.
Stay stitch around your sleeves, if necessary. I definitely had to one the brown one. I sewed a medium long stitch near the edge of the sleeve. The stitch gave it more stability so I could fold it under twice to finish the edge.
You might have to adjust the neckline a bit if you want to keep the original finished neck edge (like on the blue one).
Try not to cut your knits too soon before you can sew them. Some knits curl in a lot.
