Kasabian, who opened this year's BAFTAs, hit the red carpet in their formal wear. Well, sort of.
Serge, the band's guitarist, donned a T-shirt with the words "black tie".
And he didn't wear formal trousers either, instead he opted for some skeleton jeans.
If you think the outfit looks familiar, this is what Serge wore in Kasabian's video for "eez-eh".
In fact it's pretty much Serge's staple outfit, so we shouldn't be that surprised by his choice. Speaking to BBC Radio 1 last summer he said: "I've got about 18 T-shirts with various words".
And to top off his red carpet look, he added this fluffy clip-on tail.
