I had already cut out the hem facings before fitting the side seams, so I had to add 3/8-inch seam to the center front and center back. I also wrote a note about there being a mistake in the back hem facing for sizes 0 to 4. But I don't remember what that was. Guess that's what I get for typing this nearly a year later.
Mikey says he really likes this top, and although I don't love it, I rotated into the work wardrobe a few times this summer. It would have been terrible in Kansas City's humid summers, but here it was a nice option on a warm day. I'll definitely choose a drapier fabric next time.
