I don't always want a zipper closure on the Quincy Top. I can't always find the exact color and length of separating zipper - at least quickly. Also, the fabric that I used, EBL004 Linen - Frosty Pink & Green, was so soft and semi-sheer, that I thought a zipper would be too heavy. So it is possible to convert the front to a button closure with some simple adjustments.
