Where do you wear your pedometer?

i'm just starting to try to wear mine on a regular basis. i have tried to put it on my waist band any number of ways but as soon as i bend over or basicly anything other than just be in an upright position, it falls straight off! i'm wondering if this happens a lot to everyone or what? and if it does, where else can you put it so it doesn't fall of so much? could i put it on my bra strap and it still be accurate?

ps. i have one that measures miles, how many miles should be a good basic daily goal?
