Maybe, but you can prbably get a police costume @ a regular costume shop
Not an official uniform but you would be allowed to wear one one if it is from a costume shop etc- so long as you did not try to make any effort to convey the belief to anyone that you WERE an officer.
Costume shop
You can get the infant costume at Jester's Costume Shop. The baby costume is not available because Fantage quit selling it at the shop. I believe the only infant costume is the Pajama Girl.
You can find an inexpensive lady bug costume at a local discount shop. You can also try a party shop or a costume shop to make sure you have the best.
The Costume Shop - 2014 was released on: USA: 10 January 2014
Costume shop in your local area or if not on ebay
A child sized police costume can be found at the Costume Supercenter website and department stores such as Target. Halloween Express is a store that also sells child sized police costumes.
You get the ghost costume in the gift shop but Halloween already pasted so the gift shop now won't have the ghost costume, I think you'll have to wait until next Halloween to get the ghost costume.
