I was unable to locate the matching skirt so the price is unknown.
The top was easy to locate a pattern. Here it is:
This is the About Town Popover pattern by Pattern Emporum. The fabric for the pattern is light to mid-weight. I think this is a perfect match to the silhouette of the inspiration photo.
There isn't any way to know how heavy the inspiration top is. So, I suppose you would just need to do the best you can do. Of course that is what we do best, create the way we want.
As for the skirt, I think I long straight skirt would work. Pattern might be tougher as we can not see the back of the skirt. It seems that there has to be a walking pleat or opening in the back. Here is a pattern that might work:
This is the Merchant & Mills Penna Pencil Skirt. Appropriate fabric would be 4 to 6 ounces. The front slit could be moved to the back or made as is.
I do not think that you could miss with as a set. Make sure that the color matches within the your wardrobe and you will be able wear the individual pieces with multiple items.
Hope you are inspired to make something wonderful.
Happy Sewing!
