At 5'4, I'm in that no-man's-land where regular-length pants are just a hair too long and ankle-length pants show off just a bit too much ankle to be fashionable. Lucky for me (and anyone else who hates dragging the cuffs of their jeans through the muck), there are some great options for hemming that won't permanently alter your pants.
Best for Fashionistas: CityClips ($35)
These magnetized strips that hold up outward or inward rolls are available with all kinds of cute button and bead adornments. When you want it to be known that you're both frugal and stylin' (like when you convert those jeans into capris), CityClips are the way to go.
Best for Girls Who Plan Ahead: N*Jeanious ($12 for 20 strips)
This invisible hemming tape requires you to turn your jeans inside out for the most discreet altering, so if you know you're wearing flats to work but want to bust out the heels for happy hour, N*Jeanious is your best bet. Do your hemming in the morning, then peel off, toss, and quick-change the shoes.
Best for Clotheshorses: Zakkers ($27-$30)
Zakkerz has magnetized hemming strips to match every last pair of pants in your overflowing closet. Need to give your jeans a little lift? Denim-colored long Zakkerz gets the job done, adding a bit more strength to hold up the heavy fabric. Want to shorten your white linen pants? There are white Zakkerz in the regular length, perfect for supporting flimsier fabrics that need reinforcement around the roll-up.
