The dress does have a very deep V in the front so something needs to be worn under it (unless you're very brave). So, rather than have to wear another shirt underneath mine, I chose to add a panel in the front to cover most of the V. I don't always want the additional layers of another shirt. But, here I show that it is easily done.
This picture is with a self-drafted quick cape that I made last year (I think). It's about 30 degrees and breezy, so I was freezing.
This dress is simple enough to dress up or wear casually. It can also be made with 3/4 sleeves and longer at the bottom (more of a midi length dress).
Quick and practical...that's my kind of sewing!
