This is one of the pieces that depend on fabric more than in craftwomanship ;-)
I bought this at the beginning of the summer and I have been thinking about the superior piece since. First I imagined it attached to the upper part of some old black jeans. I could not accept the idea of the little flounces around my already flounced belly! Finally I saw this somewhere and I welcomed it as the perfect solution: some 12 cm of black lycra, with a thick elastic band in the upper part, to be situated in my lower waist, and... voilà! It was done in 1 hour!
