First I turned the mini skirt inside-out and laid a pair of Olivia's existing leggings on top, with one side matching up with the edge of the skirt (that way I could use the already sewn edge and wouldn't have to do it myself).
I pinned around the outsides and along the inner legs of the existing leggings.
I cut out around the outside of the pin line and then sewed along it. The great thing about using a mini skirt is that you don't have to make the waist or hem the bottoms since they are already there!
Turn those bad boys right side out and BAM! Killer baby leggings.
Livi wanted to showcase the full effect of the leggings. White baby belly included.
