This is such a cute pattern, and, I think, understated. As in, it doesn't SCREAM vintage. It's smart, and vintage looking, but not super obvious, which I like. It's Simplicity 4047, but last time I looked, it was out of print. I got my copy off ebay for about $15.
I sewed a blouse from it over a year ago, and really liked the fabric I chose, but I didn't take any detailed measurements as it was only my second proper sewing attempt and it was too big around & too short... and kind of reminded me of hospital scrubs. I still wear it on occasion, but when I recently sewed another version, I really fell in love. I added FOUR, yes 4, inches in length to this pattern, and sewed a smaller size, and I love it. I also lowered the neckline by about 2 inches, so it didn't feel so hospital-ish. I picked a nice material, and actually spent more than I would normally for fabric, but I am so glad I did. It's a light cotton, with small embroidered flowers on it. Because this fabric was lighter, I used a light-weight interfacing, and also made the neckline interfacing panel a lot narrower, as I didn't want to be able to see through the blouse and have my interfacing so visible. There is also a ring of interfacing along the sleeve edge to give it some shape, but I didn't add it, instead keeping the sleeves loose. They have less shape, but then they also fit nicely into the sleeves of a cardigan, not showing lumps through. I made the sash a few inches longer as well, so I had the option to tie it in a bow.
So, after a day of sewing, I needed to test out the new threads, and we took our respective modes of transport to a local cafe.
Overall, I am very pleased with the results, and taken out on a test run, everything worked great! I could ride bike, sit & eat, and no seams fell apart :)
(We live near a regional airport & often get to see pilots in training, jets, carriers, all sorts of aircraft. today we got to watch these little guys fly in formation, though I only got the camera out as they were looping back for landing. Supposedly the fighter pilots train in these to practice formation. A few weeks back, I got to watch the new Australian fighter jets come and say hello to the guys in the tower. As much as living near an airport SUCKS, you do get to see some fun stuff every so often).
