After securing our Real Housewives Costume Set in Blonde, decide which blonde bombshell's attitude you'll be taking. Add wine and cigarettes for Kim, quips-a-plenty for Tamra, or a toaster oven cookbook and you're Sonja.
Start with an expertly styled bob haircut or wig, then layer on several pounds of layers of asymmetrical clothing in shades of grey/black/neutral. Spend the evening reapplying red lipstick and discussing your distaste for unattractive men and wines from Oregon.
Think about it this way: you only really need the dog head and paw pieces of the costume, because the precious pup is hairless elsewhere. Once you have those necessities, put on your finest velvet pjs and Lisa Vanderpump might start carrying you around on accident.
A great costume for those only having time to stop at the office supply store before hitting the party. Gather about 300 index cards and an encyclopedic knowledge of cinema, curse words, and tattoos and you're most of the way to James Lipton. Add a suit, glasses, beard, and dramatic PACE-style lighting and you're Oscar-worthy.
