The sequin long-sleeve shirt mini lists a button-front closure and a loose fit. Buttons create a different fit question from a zipper: the front must close without pulling apart when you move. The 26.77–27.56 in body length is a separate coverage check.

Check the front while moving

Button a shirt dress you already own over the underlayer you plan to wear. Sit, reach forward and turn to see where gaps appear. Compare its finished bust and button spacing with a current laid-flat measurement of this dress. Ask for a close photo of the button placket in the chosen size, especially across the chest and hip, and whether any inner fastening prevents gaps. The listing does not give button count or spacing.

Use the four chart columns

S lists bust/shoulder/sleeve/body length 41.73/18.7/21.65/26.77 in; M is 43.31/19.29/22.05/27.17; L is 44.88/19.88/22.44/27.56. Bust grows 3.15 in from S to L, but length grows only 0.79 in. If a larger size is needed to keep the placket flat, do not expect a much longer hem automatically. Ask where the body-length measurement begins, and compare that point with your reference shirt dress while standing and sitting.

Confirm the version being ordered

Green, Blue and Pink are selectable. The source says sequin-paneled all over and names polyester and spandex without proportions, but it does not describe lining or sequins’ placement by color. Ask for an interior view and a current photo of your selected color. No stretch amount or wear performance is measured in the listing.
