How to lengthen skirt

Hi all - I am making a Catolie party dress and have run into a problem by having run out of fabric. Dress is at: http://www.welcometothemousehouse.com/2013/12/the-caroline-party-dress-its-here.html I am using this (https://www.fabric.com/buy/dh-362/valori-wells-nest-cotton-voile-berries-rose) fabric for the skirt (pieced together from small pieces I had. I was fixated on using this fabric!) and a pink honeycomb for the top with a white eyelet collar. I'm about 1-2 inches short on the skirt. I'd love any ideas. Maybe finish with double folded bias to lengthen? Or use the dark pink honeycomb at the bottom in some way, either ruffled or like an underskirt peeking out? Just looking for an idea that will look intentional and not like A jigsaw puzzle. I've already had to piece together the Valori Wells fabric from some narrow remnants, trying to match the pattern. Maybe I should just suck up the cost and buy fabric to do this properly? (Where's the fun in that? ;) ) Thanks!!
