Black and Red faux 2 piece dress

Looks like a dress with matching cardigan, but it's really all one piece! Top is black knit material with 3/4 length sleeves. Pencil skirt is a rayon blend in red and black houndstooth. Smaller houndstooth pattern accent on "cardigan" coordinates with the skirt. Back zipper Arms measure about 16 1/2" from shoulder. Mini skirt measures not quite 23" from slightly high waist. Labeled 3X, wears more like a 1X or XL. Washed once but never worn, slightly short for my taste. Excellent condition, no stains, rips, or snags.
