Your questions about finding flattering trousers, answered.
Q. Where exactly should my pant hem hit?
To create the longest possible line, pants should be an inch from the floor, with the hem breaking over the instep.
One option is to buy two pairs of the same pants and hem one for heels and the other for flats, but you can fudge a happy medium by wearing the same pair of pants with flats and up to a two-inch kitten heel―but no higher, suggests Allison Berlin, founder of the New York fashion-consulting firm Style Made Simple.
When switching from heels to flats, a quick fix is Zakkerz ($29, zakkerz.com), which secure rolled-up cuffs using magnets.
