Dress inconspicuously
From KGB Wiki
A phrase often said in invitation to the Underground Tour.
"How do I dress inconspicuously?" you ask? Well, just think of spies: they wear trench coats, fedoras, big sunglasses... and no one can ever point them out in a crowd or a field of sunflowers.
Pieces that would be considered inconspicuous:
-fedoras
-trench coats
-lab coats
-goggles
-sunglasses
-brightly colored clothing (try tangerine, purple, or sea foam green)
-corsets
-suits
-fancy dresses
-the highest of heels
-top hats
-fishnets
-banana costumes
-pumpkin hats
