Downsizing figures

When is a perfect size 6 not so perfect? When it’s really a size 8. Confused? Join the club. If you’re a woman–or you’ve ever tried shopping for your favorite femme–you already know that judging fit by eyeballing the item or checking the tag is a crapshoot. A size 6 Donna Karan skirt may fit like a charm. But if you try that same size in something like Guess? or BCBG, you may wonder when you managed to pack on an extra five pounds.
