Literal translation
did you burst open the wardrobe?
Meaning
to be dressed to the nines
Explanation
Said to someone very well dressed, literally did you break your wardrobe? The ironic image assumes that if the person is wearing so many fine clothes at once, it must be because there is nowhere left to store them, the wardrobe having given way under the weight. It is asked directly, in the informal second person, to someone close, in the spirit of a light hearted jab among friends. A variant exists, to have kicked the wardrobe, for the same result.
