How to put it together

1
Select your theme based on what you own: a flannel shirt for a lumberjack, a suit for a secret agent, or a plain tee with sunglasses for a tech mogul.
2
Put on your base layer, such as a solid neutral t-shirt and classic blue jeans or dark trousers.
3
Add the defining outer layer, like your plaid flannel, a leather jacket, or a sharp blazer.
4
Put on appropriate footwear, ensuring it matches the vibe of the character (boots for rugged, dress shoes for formal).
5
Incorporate one or two key props, like a pair of aviator sunglasses, a clipboard, or a simple hat to sell the concept.
6
Style your hair quickly with a bit of pomade or throw on a baseball cap if you are short on time.

Makeup & hair

Prioritize comfort by choosing clothes you already know fit well and are comfortable for standing or walking.
Keep it clean and neat; even a simple t-shirt and jeans look like a deliberate costume if the clothes are freshly ironed and clean.
Use what you have first before buying anything, as most last-minute ideas can be built entirely from a standard wardrobe.
