re the overhang on jeans, of love handles and tummys, recently heard them referred to as 'muffin tops' (picture your morning muffin, and that spot just above the paper case....).
I'm all for personal expression, but in a professional business environment I question some of the clothing that people think appropriate. Even if you don't meet the public, if customers / supplier ever visit your work place you should be appropriately dressed, casual friday shouldn't mean any old thing, it should mean smart but slightly more casual clothes (a co-worker defines casual smart as any Ralph Lauren ad).
