By wardrobe, do you possibly mean a chiffarobe? I'm native English speaker from the US, but the only way I've ever used the word "wardrobe" is to say things like "my work wardrobe" or "my travel wardrobe", or "professional wardrobe" - basically it's the collection of clothes one owns.
Well, looking at what Google Graphics shows me, I'd translate "chiffarobe" to "szafka". "szafa" is rather bigger. And Google Graphics shows me exactly what I'd expect when I search for "wardrobe".
The 'collection of clothes' meaning translates to "garderoba", and it can also mean the room one uses for keeping their clothes. Also the... dressing room (?) for the actors in the theatre.
