Hai there!

Me & friends are looking for a shop where we can find masks and other halloween-costumes!

Logically there should be such a store somewhere, we just need to find it!

appreciate all answers baibai =)

Carrefour, Metro, Wal-mart.

They all carry cheap basic stuff, masks are kids size but some might fit.

Not ever seen costume rental in any city apart from Shanghai.

Rent a full body costume from any good costume shops in donwtown could also be an impressive option. They might not have Halloween them costume but you could probably find something suitable with a pinch of creativity using accessories.

There is a full-fledged costume shop in the north. It's on Bei Chen Da Dao East. From Metro - go east about 2 blocks and start looking on north side of street. There are two big windows full of costumes of all types.
