Here are the specs, also recorded in the description on Flickr.
This is a Hanne Falkenberg design called Mermaid, in colorway #3, size Medium. I started it in late October 2006 and finished February 25, 2007.
Mermaid is available only as a kit that includes the instructions and yarn, a 4-ply Shetland wool. It is knit sideways and entirely in garter stitch. I used US 3 (3.25 mm) Addi-Turbo needles to get gauge. The body is worked in one piece with short rowed gussets giving it a marvelous shape.
I originally bought the kit at Stitches Midwest from Yarn Barn of Kansas in 2005. I finally felt able to tackle such fine work a little over a year later. The small gauge and colorwork were a first for me, but the results are a lovely heirloom garment.
