What is on Alan's shirt in The Hangover?

Alan wears a tan t-shirt featuring a black graphic of a human face that blends upward into bare tree branches, often referred to as the 'Treehead' shirt.

How do you make the baby for the costume?

You can use a standard plastic baby doll, dress it in a light blue knit beanie, and tape a small pair of toy sunglasses to its face before placing it in the carrier.

Is this costume comfortable for hot weather?

Yes, because it consists of a t-shirt and cargo shorts, it is very breathable, though the synthetic beard can get warm over the course of the night.

Put on the gold-rimmed aviator sunglasses.
4
Strap the white baby carrier onto your chest, adjusting the shoulder straps for a secure fit.
5
Dress the plastic baby doll in a blue knit beanie and a small pair of sunglasses.

Place the baby doll securely inside the front-facing carrier so it faces outward.

Makeup & hair

No makeup is needed, as the bushy brown beard and wig do all the work. Ensure the wig looks slightly unkempt and bedheaded to match Alan's chaotic energy.

Keep a spare pair of cheap sunglasses in case you lose yours while partying.
Practice your best deadpan delivery of Alan's classic lines to really sell the character.
