Need some help!

I am working on this pattern. As noted on the site and on the pattern, the side seams are not seams at all but darts. One side is the side opening and you insert a zipper here. I have inserted the zipper but the end of the zipper/dart looks a little wonky. I should have taken a photo. I can not figure out how to get this to lie flat. If anyone else here has made this skirt, could you email me so I can contact you to ask additional questions. Email is lwlamona@yahoo.com.

Thanks for your help!
