I omitted the zipper - no need for it.
The only downside to this dress is the seam at the waist. I mean, it's no big deal, but there's no real reason for it that I can figure. The top isn't cut on the bias or anything and it just makes a little extra fabric seam where no one needs extra fabric. I wore this dress out to dinner with my hubby. I wore a belt with it to cover the seam, but I think it's ok without one too.
One more thing - I think I have abnormally long thighs and short calves or something. The length looks so long, but it's just to the knee. I seem to hem all my skirts above the knee cause I think that's my most flattering length, but a girl's gotta have some knee-covering skirts!
