It's easy to see why the tabard idea took off for women in the 1970's--it's sporty, folky-eclectic, and an easy make-it-yourself vest/pullover/tunic. Even in the medieval wiki-pics it looks like a simple drop-shoulder construction. Leaving the sides unseamed is a distinguishing feature of the tabard, dating all the way to 1300 AD.
Below is a short list of my favorite features of this "Baroque Tabard" free pattern, available here. I personally like to hear what designers think about their own designs and what the backstory is. If this is a "tooting one's horn" that you, dear reader, find annoying, then you can stop reading now and you won't miss anything, and I appreciate your visit today.
the tunic is worked in vertical rows of hdc so that the subtle color-striping built in to the yarn looks the same for any size including plus-sizes (when a self-striping yarn is worked in horizontal rows, the effect is not the same for plus-sizes.) The vertical lines also make the tabard style more flattering.
- I totally invented the lace tie stitch pattern and significantly changed the classic “picot fans” stitch pattern of the sleeves. I love the super-lacy sleeves (that's where the "baroque" part comes in even though Queen Eleanor lived about 400 years prior to the Baroque period).
The hdc bodice works up quickly and includes simple shoulder and neck shaping. This keeps the traditional drop-shoulder tabard from looking boxy or clunky.
I liked being able to make the seams decorative. It is surface-crocheted reverse single crochet (aka "crab stitch").
