I found this interesting coat and was kinda shocked by the price. Here you go:
This is the Reversible Double-faced Cashmere Coat & Scarf by Lafayette 148 New York. Price tag: $4,298.00. Details: crew neck, concealed snap front, long sleeves, side pockets, hem hits around the knee, a-line fit, cashmere, scarf with fringe. Length 37 1/2-inches from shoulder to hem.
Can you believe that price? I have a pattern for you:
This is the Ivy Unlined Scarf Jacket pdf pattern by Seamwork. The basics of the inspiration photo are here. The closure is different and the scarf ends are different but you certainly get the look and feel.
I even found double-faced cashmere at this site. Honestly, I do not know anything about that site but if this is the look you are going for, it would be worth your time to investigate it. The jacket & scarf take 4 yards of fabric. The fabric at that site is about $80 per yard and look at all those colors. Now, if your a little hesitant to purchase from someone so far away, Etsy also has some double-faced cashmere. It is a different price point.
Hope you are inspired to create something wonderful.
Happy Stitching!
