I attached the overlay front and back to each other and sewed up the side seams. I did the same with the black main fabric and the waistband pieces. I then turned the seamed sides in, placed the green skirt pieces on top of the black skirt. I carefully pinned the waistband piece, folded in half, to the main body and sewed around. Last step was hemming both skirt bottoms. Since my overlay was cut slightly longer to provide a sheer bottom, both were hemmed separately.
The skirt is a great somewhat dressy piece to add to my closet and altogether, cost about $15-20 total. Such a steal!! I used less 1 yard of both the lace and the black knit. Both were purchased at my local JoAnn's this spring.
I paired it with a thrifted shirt from ThredUP, Cole Haan heels from my closet (DSW discount pair!), a Stella and Dot necklace, bangles my kids gave me for Mother's Day (I think they are Five Below!) and a Vera Bradley clutch from the outlet sale. I felt sexy and well dressed!
