I bought this costume earlier this year from ebay at a cost of around £15 + delivery charges, which I think was around £5. It was an absolute scream of a hit - everyone we came across seemed to never have seen anything like it before. I now see it on Amazon priced at £19.99 with free delivery option.
~WELL HOWDY PARTNER~
I must admit for £15 I wasn't sure what to expect - it wasn't a lot of money for such a 'substantial' outfit! What you get is a costume made of a synthetic material, a bit like a thin pac-a-mac, all stitched together, comprising a horse and a pair of legs... Stay with me here! You put your legs into the horse's back legs and pull the costume up like a pair of trousers. There is a strap to hold the horse's head up with. Inside the costume, with a belt clip, is the power pack. This needs 4x AA batteries (not included) and has an on-off switch. Once you are in the horse's legs (!) you pull the drawstrings at the ankles and around the waist securely (not necessarily air-tight!), and these are secured with the usual spring-type toggles. You then switch the power pack on, and hey-presto, your horse inflates!! You then have the look as in the image above, with a horse rearing up on its back legs with you riding it. It's such a simple/silly costume yet it is really funny when the person is wearing it.
The horse is coloured pale brown and beige and the cowboy legs are blue with a little pair of black boots on the feet. The horse has an adorable comic face with big ears, and can't fail to raise a smile on its own. It's a one-size fits all costume, the picture on the packaging showed a man wearing it, yet the legs weren't so long that they looked silly on a woman (being short!).
The horse inflates in less than a couple of minutes. When inflated it's still soft and it's extremely lightweight. After a little while, the horse will start to lose it's air but when that happens, the power pack automatically kicks in to reinflate it in seconds, and this process goes on periodically as long as the batteries will last. It does make a slight buzzing noise (and vibrates a bit!) but this is hardly noticeable when a party is going on or you're in a bar.
~RIDIN' ON INTO TOWN~
We took this costume with us on our girls holiday this year when we have a fancy dress theme one night - which brings me to another thing to mention, it folds really flat - and takes up very little space. When we went out into town, the looks and comments we got that night were so many, plenty of people were asking for photos and asking where we'd had it from.
It also comes with a floppy cowboy hat, but you can buy much better cowboy hats from Poundland which are a better look, so that's a bit of a waste, and would have let the costume down a bit. You also need to be aware that the costume doesn't come with a top, so you need to invest in some sort of cowboy upper-half attire.
The other main points to consider are: that you can't see where you're going very well, and you need to take care where you're walking (don't start off drunk!); the batteries were not 100% new but they did not last the whole night, it must use a fair bit of power, so if a long night is planned, take spares or you'll be taking a droopy horse home; and finally the horse does not fit easily and comfortably into Portugese bar ladies toilet cubicles.
