It's the Stellar Vest. The pattern includes a dress option (with pockets) and is designed to be layered. It's a quick, easy sew and doesn't use a great deal of fabric. (About a yard for Lee's size.)
For this test version, I used two of Ryan's old vests. I probably could have used just one vest and kept the original arm and neck bands, but because I was testing it was important to stick to the pattern's measurements and not fiddle with widths.
Here's what I really liked: the proportions of the bands are scaled appropriately, the pattern and instructions are well executed, the fit is just right for layering, and it's a great wardrobe staple.
The only challenge I had was centering the "V" and making sure it was neat. And not melting the synthetic fabric when I pressed it.
Pattern: Stellar's Vest and Dress from Elegance & Elephants
Fabric: Upcycled Docker's vest
Thoughts: I'll be using this pattern for the boys' Spring photos outfit! I'll choose the fabric to coordinate with Eliza's dress, and the vest will be layered over a plain white dress shirt and chino pants. Vests are kind of our thing for Spring photos.
Now if I could just find a location as gorgeous as Biltmore. . . (here are our last three years' photos)
