During the Halloween season, I find the best place to go for costumes with the biggest selection is Party City. They transform over half of their store into a Halloween costume showcase.
One of the best places to get any type of costume is Party City. They have a huge selection of costumes in store and if you do not see it in store, it will definitely be available online.
Walmart has a huge selection.
The best place to look would be an online auction site such as eBay where local sellers will be found. The La-z-boy website has the biggest selection though and would deliver to Regina.
I think it just depends on what theme you are looking for. Partycity.com, Orientaltrading.com, and partyamerica.com are three of the biggest online companies who offer tons of options.
If you want the real deal, go to the source and get a branded Disney costume from their store. But for a look-alike style try www.orientaltrading.com/Belle
The best thing to do is buy your Elmo costume from an officially licensed store. This can be through a local or online dealer.
You can find a good hippie costume at costume express. They carry a bunch of different costumes and they are just a costume store so they would be the best place to look for your hippie costume.

Any local costume shop or Halloween store would be best to buying a pilot's costume. However, be noted that impersonating a pilot at an airport is a federal offense.
Many stores offer complete cookware sets, but one should look at a store designed specifically for cookware and home accessories for the biggest selection.
You can find an Ariel costume ready to be enjoyed at a Disney Store near you, or online. Many other outlets, such as costume stores may have selections you will enjoy.
Go to your local thrift store or costume shop to find a superhero costume. Or if you would like a specific super hero, go to http://ebay.com/ to search for your character.
