I love vintage sewing patterns because I always have this image in my mind of the perfect vintage something and I can't actually find the item. I'm always dreaming up 70s era tunic tops but most of the ones that exist are polyester, which feels icky and hot in summer.
By the way, if you are planning to shop vintage patterns, take note of the measurements. Sizing was different 30 years ago, a vintage size 12 is more like a modern size 6. Etsy is a great source for vintage patterns, I can (and do) spend hours sifting through them, but I've also had luck at thrift stores.
I skipped the belt for now. I also didn't even bother to finish the bottom or the sleeve edges, I'm just going to leave them raw. The fabric trim is vintage and I've been holding on to it for years. (PS - those little dark dots aren't stains on the shirt, they are water drops from my wet hair.)
My sewing as usual isn't perfect, but I'm pretty happy with this particular shirt. I'm slowly learning to sew stretchy knit fabrics and get comfortable with it. Not sure why I was afraid of it for so long! Considering that cotton jersey is all I want to wear most of the year when it is hot I think I'll be doing more of it.
Now I just need to find more patterns...
