I am reading the script of a TV series "How I Met Your Mother"

The script has this sentence:

Hey, you want to do somethin' tonight? Okay, meet me at the bar in 15 minutes. And suit up! Where's your suit? Just once, when I say suit up, I wish you'd put on a suit.

What does "suit up" means please?

I tried to use a dictionary but it seems it is not a formal phrase.


In that context, "How I Met Your Mother", Barney literally and specifically means put on a suit, with a jacket and tie.

In other contexts, it means 'prepare for an activity by putting on the appropriate clothes, uniform or equipment.'

  • So it seems you have watched this series. Do you suggest me to watch it in order to learn more english? and is it a funny tv series like Friends or not ? – Simeoni Peraparota Apr 21 '14 at 21:16
  • Sure, it's a pretty good show. It can be very witty at times so if you're learning English, the captions will help a lot. – Johns-305 Apr 21 '14 at 21:29

The above answers are correct, but the expression usually has a sense of specialized clothing that has a protective purpose.

For example, a diver might suit up with a wetsuit, or an astronaut would suit up with a space suit.


it means : to get ready for an activity by putting on a uniform or special clothes.

Suit up, and we go.
