Please review the last photo carefully. I have placed a piece of white fabric underneath the front opening for contrast. The front button closure brings 2 fabric edges together and might result in a "peek-a-boo" feature that you should note. A slip or camisole worn beneath could address any modesty concerns.
Sleeves extend below elbows and dress length is approximately mid-calf or longer depending on the height of the wearer.
Measurements are approximate because knit fabric stretches easily.
21" armhole to armhole
45" at hem
16" sleeve length from shoulder
48" back neckline to hem
