Nancy is Betty’s twin sister ( no, not identical). Nancy, like Betty, is no frump. You might think she is the same as Betty but you’d be wrong. Yes Nancy’s dress is much the same shape but the differences are in the knitting. Pink, red. Checks, stripes. Right side of stock ninety, wrong side of stockinette. Petticoat, no petticoat. Beads, no beads. All these things set them apart.
