Transformers are always going to be a big hit. This one is Hasbro Optimus Prime. It can change the wearers voice. There's also a button on the side that plays some pretty awesome voices and sounds. This one was one of my six year old's favourite dress up toy's. He now has some other favourites so this went onto eBay. It sold pretty much straight away. This type of mask will bring about £20.00.
Hats from TV shows such as Bob the builder and Firmean Sam are really popular with smaller children and can be picked up second hand really cheaply. They can be found at virtually every boot sale, charity shop, garage sale or auction. While these sort of dress up items won't bring in massive amounts of profit these are the bread and butter sort of items that any eBay business relies on. They sell really well in either winter or summer when parents are looking for cheap ways to entertain their kids. Buttons on top of the helmet play appropriate music and phrases from the programmes. These hats bring bout £10.00 to £12.00 each but can be picked up as cheaply as a £1.00 each
There are some great dress up accessories that will also bring good money online. These are Wolverine claws if you can find a pair they are worth much more than having just one. If you can get one it will bring £13.00 to £17.00 but two can realise anywhere from £34.00 to £40.00
