'Garderobe' is a loanword from French. It is made up of 'garder' (to guard, to store) and 'robe' (dress). Literally, then, it is a place for storing clothing.
Im Theater müssen große Taschen an der Garderobe abgegeben werden.
In the theater, large bags must be left at the cloakroom.
'Die Garderobe' as a piece of furniture is usually an open stand or a row of hooks in the hallway. The English word 'wardrobe', meaning a large, closed cabinet for clothes, is 'der Kleiderschrank' in German.
Häng deine Jacke bitte an die Garderobe.
Please hang your jacket on the coat rack.
The context reveals the meaning: In public buildings, 'Garderobe' is the checkroom counter. In the hallway of an apartment, it is the piece of furniture for hanging up jackets. If people are talking about fashion and style, it means a person's entire wardrobe.
Im Restaurant gab es leider keine Garderobe für unsere Mäntel.
Unfortunately, the restaurant didn't have a cloakroom for our coats.
When referring to the cloakroom in a public building, the typical verbs are 'abgeben' (to check in / to leave) and 'abholen' (to pick up). You leave your jacket there and pick it up again later.
Vergiss nicht, nach der Vorstellung deinen Mantel von der Garderobe abzuholen.
Don't forget to pick up your coat from the cloakroom after the performance.
In the meaning of 'clothing collection' or 'wardrobe', 'Garderobe' is often used with verbs such as 'erneuern' (to update/renew), 'ergänzen' (to add to), or 'zusammenstellen' (to put together).
Für den Winter muss ich meine Garderobe noch mit warmen Pullovern ergänzen.
For the winter, I still need to add warm sweaters to my wardrobe.
clothing
'die Kleidung' and 'die Garderobe' can both have to do with a person's clothes. 'Kleidung' generally means the things you wear. 'Garderobe', by contrast, can mean all the clothing someone owns, so more like the personal collection in their closet. That is why in everyday language you often say 'meine Kleidung' when talking about individual items or about wearing clothes. 'Meine Garderobe' sounds more like you are talking about all the clothes together, often also about style and selection. The words can be confused, but in this meaning 'Garderobe' is not simply every individual item of clothing.

Im Krankenhaus soll man bequeme Kleidung mitbringen.
