Wouldn't mind getting into the lab coat of that one.

At once a young woman in a lab coat appeared.

I turned to see an older man in a white lab coat.

The man beyond her was dressed in a white lab coat.

Next up was a safety officer, also in a lab coat.

I got up and hung my lab coat on the back of the door.

Across from them sat a woman in a white lab coat.

"And everybody thought scientists were people in white lab coats."

They both turned toward the man in the white lab coat.

She turned and saw a man in a white lab coat.
