i've tried to be pretty consistent in my weigh-in gear. around the house i usually wear a light pair of sweat pants and a t-shirt. unlike the characters on The Big Bang Theory (aside from Penny), you don't need sweaters, hoodies, jackets of multiple layers of clothes in general in SoCal. it's getting to be sweatshirt weather, but mostly at night. from birthday suit to business suit, the change on me is about 2.5-3 lbs. generally what i wear at weigh-in adds about a pound and a half. ...but i'd rather not think about the noise.
