It is a very pretty collar.
You may remember the outfit I did for the Passion For Fashion contest I participated in 2 years ago. The collar is bigger, but basically the same principle.
I have a vintage coat that I've had for some time that also has a similar collar.
But here's what I love. To obtain the shaping, there are a series of darts all around the collar. Beautiful.The collar is actually hand sewn to the back of the coat.
This collar is rather over the top, but the collar on the white coat is very sensible and pretty. I will be more than happy to do a tutorial on drafting the collar. Let me know if this is something you would like to see. The perfect coat pattern for the white coat would be the Sewaholic Robson coat. I look forward to hearing your thoughts!
