How many sprays of TF Grey Vetiver EDP do you do? I tried it today on myself instead of a test strip for the first time – smells great, but 7 sprays and I barely smell anything 3 hours later unless I stick my nose right into it. Wife doesn’t smell much either from a slight distance, but likes it up close. Is this a common issue? Could be an old tester at Sephora sitting in the bright lights?
