I've been meaning to make an Asymmetric Dress in jersey for sometime and I've finally got round to it.
The jersey I've used here is a drapey polyester/Lycra jersey from Ditto, but it would also work in a viscose jersey. The key is the drape; plain cotton jersey wouldn't have the fluidity to make the most of the gathers.
Instead of the wide elastic suggested in the pattern, I found some 3mm corded elastic for the gather details; this requires a narrower casing. Also I wanted to add a knot as shown - this requires buttonholes to feed the elastic through.
At the neck I positioned these 2.5cm from the neck edge on the front fabric piece. For the side and back gathers I chose the mid point between the points shown on the pattern. My buttonhole is small just 12mm long and to stabilise the jersey I used embroiderer's 'Stitch and Tear' backing.
For the side and back casings I used 15mm soft cotton tape, stitching down at the very edge of each side.
I made the dress up as instructed then threaded my corded elastic through, knotting each end with a loop and trimming. For the sleeve cuffs I chose 12mm elastic to balance with the narrower gathers. I shortened the sleeves by 7cm for a more summer style.
As this jersey has plenty of stretch it meant I could lengthen my dress. I like this slightly longer length with bare legs in the summer.
