Vintage Just Ducky 2 piece black & white skirt set. Top has attached fabric belt and Shoulder pads, size 12, 100% polyester. Skirt seems slightly sheer, may need to be worn with slip. Excellent pre-loved condition, no visible flaws. Please refer to photos for measurements and let me know if you have any questions! What is the name for this pattern? Polka dot Tiny squares? I love this this dress it totally reminds me of Barbie! Tags: vintage, retro, old school, design, pattern, print
