Background: In case you don’t know what a sheath is, it’s a cocktail dress. Normally this type of dress is sleeveless and knee length. Think Jackie Onassis. This should help:

I attended a Christmas party back in December and one of the guests had on an off while sheath. This is a classic dress, as you see above, one you’d wear with a dainty shoe. Not this lady, she had on black solid, not too fancy (not even a pointy toe) knee high boots. It was a fashion don’t like I haven’t seen in a while. Poor thing, I think What Not to Wear‘s Stacy and Clinton need to pay her a visit.
