Vintage 90's Geometric Print Silk Maxi Wrap Skirt

I love the funky geometric print but have resigned myself to the fact that this is just too small for me. I added a second button to try to add a little more room to the waist, but still too small for me. True wrap style skirt, fully lined. First, the skirt is buttoned, and then there is an extended "flap" with a long ribbon that you wrap around the waist (through belt loops) and then tie with the remaining ribbon that is sewn in the opposite side of the skirt. Color is a greyish blue against a blackish/blueish background. Vintage size 6 but runs very small by today's standards, probably closer to a size 0. Please refer to the following measurements: Waist measures approx 13" with the original button or 14" with my added button, but there is absolutely no stretch. Total length is approx 36".
