Inflatable Halloween costumes are blow-up novelty costumes. Popular inflatable costumes include sumo wrestlers, pumpkins, the Incredible Hulk and over-sized hula dancers or ballerinas. There are even inflatable costumes that look like animals (like an inflatable cow costume or horse and rider). Inflatable Halloween costume accessories can be purchased separately, they include inflatable hats or big shoes like clown shoes.

Inflatable costumes can give the appearance that the costume-wearer is heavy, has huge muscles or can allow the person wearing it to take on a whole new shape. Keep in mind that inflatable costumes add extra bulk, so moving around (or sitting) may be a bit difficult, depending on the costume. The costumes can be bought at major retailers like Toys R Us or through costume websites or sites like Amazon.com.

The inflatable costumes range in price. On the lower end, an inflatable costume can cost about $25 while more elaborate or higher quality inflatable costumes can be upwards of $100. There are two types of inflatable costumes; those that you must manually blow up and those that use motorized fans. When shopping online for inflatable costumes, check to see it the store accepts coupon codes.

Some inflatable Halloween costumes can be blown up the old fashioned way, just like blowing up any inflatable children's toy or a balloon. Other Inflatable costumes can be inflated using a special fan. The costumes that use fans usually include the special inflating fan, which runs on batteries. In most cases, the batteries are not included.http://www.spirithalloween.com/product/captain-america-inflatable-child-costume/

To inflate the costume, it must be put on first. Simply turn the fan on and most costumes (using an inflating fan) will blow up in just a few seconds. The costume will stay inflated as long as the fan is running.http://www.buycostumes.com/Illusion-Ollie-Ostrich-Adult-Costume/31976/ProductDetail.aspx?REF=AFC-datafeed&AID=10273928&PID=2100672&SID=NAT120543-sc30543373
