How to be “preppy”

Where do all the girls who are “preppy”’get their stuff? There are some girls out there who thrift or score great deals on things. I just want to know.. what styles do you look for when shopping? Colors? Do you paint your nails? Fix your hair everyday? Treat your hair? Perfume? Chapstick? I always see girls out in public and wonder where they get all the “fab” stuff. Everything from their kids’ clothes to their own. Where do you buy home decor? How do you get your house to smell amazing and fresh all the time with even 2 younger boys?! Do you make your husband keep up on trimming his beard? Do you help him pick his clothes out? I want people to look at us in public and think we are THAT family that is fabulous
