Why: a thick calf in a medium-length skirt reminds us of an iceberg, only in this case it's the disproportionately large under-belly of it that's on display.
or
Why: a cross-cut fabric is born to cling seductively to the body. This means that anything appearing from below the hem will look huge by comparison.
and
Why: the only things poking out from underneath will be your podgy ankles, making their very existence the sad focal point of your outfit.


Why: why: the wider the skirt the slimmer the ankle and calf will appear.
