White Doc/Lab Coat &/or Stethoscope (+/- 20 miles from Sunnyvale)

Hi, I'm looking for a unisex/generic white doctor/lab coat (hopefully not too large, I'm a medium-sized woman) and/or stethoscope -- doesn't have to be working/need it as a prop. Not for halloween! I'm an actor, going to do a public service announcement video for a non-profit, and I'd have to provide my own lab coat... I'm OK with borrowing as well. Thank you!
