There are definite upsides to wearing a Snuggie: You can eat all the cake you want. And sun damage isn’t your problem. Step away from the slanket, Whiteout, and head to The Spa at The Crescent, where the St. Tropez spray tan awaits. After putting on paper panties (or go commando, for a line-free look), step into the three-sided booth, where a technician points at you with an airbrush while a snazzy airflow system pulls away the overspray for a more even result. For now, anyone can get the spray tan, as well as package-deal additions (body scrub, foot massage), at member prices — 20 percent off what the public usually pays — so you can indulge your need for a springtime glow. And give new meaning to Easy-Bake. Available at The Spa at The Crescent, 400 Crescent Court (214-871-3232 or rosewoodcrescent.com).
