Christmas is a very busy and happy time for London.
The Natural History Museum is celebrating Christmas too.
They are dressing their T-Rex in a giant Christmas jumper.
The giant jumper is made from recycled materials and has dinosaurs on it.
The jumper has zips, so helpers can put it on easily.
The T-rex is also wearing a Santa hat too.
He looks like the design on his jumper.
Sam Barnes tells us why the jumper is important.
The T-Rex's dinosaur jumper also comes in human sizes.
The museum shop sells jumpers with matching socks, scarves and hats.
They are fun, but also serious.
The shop makes money for the museum.
The Natural History Museum is famous around the world for studying plants and animals.
They publish 700 science papers a year.
The money from the jumper sales supports the museum's research.
T-Rex looks lovely in its dinosaur jumper.
Next year, there'll be a different design.
There are a lot of other animals to choose from.
