How’s this for a nice change of pace from book groups or coffee klatsches: home spa parties. Gather your girlfriends (hey, go ahead and invite the guy friends, too) and call Primp In-Home and all the salon and spa services you desire will come to you. Anna Koffler and Jass Babin started the company in New York City in 2010 and have just branched out to Westchester (bless you, ladies!). For a complete menu and prices, visit primpinhome.com or call (212) 217-6038.
