Whether you're in need of an unusual Halloween costume, or just looking for a way to impress the socialist woman in your life, you may need to know how to dress like a Communist. Of course, not all Communists dress exactly the same, but there are some similarities that you can play on to look your Socialist best. Just be aware that dressing like a Communist may bring you some negative attention from some.
Allow your facial hair to grow. A beard is your best option. You can maintain and trim it, but if you want to let it grow long and bushy, a la Marx, feel free to do so.
Throw on ill-fitting jeans or khaki pants. You're a Communist now, you don't have the inclination to buy pants that fit you well. Just as long as they cover you up they're doing their job just find.
Wear a plain, solid colored, button-down work shirt. Beige or dark blue are good color choices.
Don boots. They should look like you haven't cleaned them up since you bought them years ago.
Sport a plain, beat-up looking overcoat. It should be warm and practical, and not all that easy on the eyes.
Carry a prop. If you're looking to dress like a Communist for a Halloween party, an appropriate prop would be "The Communist Manifesto," by Karl Marx.
Be aware that Communists aren't the most popular people in many countries. Be aware that you may be bringing yourself some trouble if you dress like a Communist.
