When it comes to jeans, you’ve got double vision: You need two pairs ready to roll at all times (one for flats, another for heels).Hem Gems solve the denim dilemma. The ingenious little studs are available in four styles (we prefer the classic rivets) and let you doctor any pair of pants in a snap (literally).Just fold your jeans to the desired length, clutch the seam, and tuck the cuff up and inside. Fasten a Gem to the front, back, and either side of your pant leg.The result: a perfect fit with no fraying. And at just $20 for an eight-pack, they’re a lot less pricey than going to a tailor. Which has us doubly excited.Available online at hemgems.com.Photo: Courtesy of Hem GemsUp to 60% off Tom TomArchitect-turned-designer Elena Coleman knows how to construct a good accessory.
