Hi the technical terms you are looking for in American are formal wear rental (not hire) or tuxedo rental if you want to search out local comanies on google.Relying on my memory of shops there are two main places in the Kissimmee area that I can think of and I have listed the websites below. Justtux is near the Florida mall and is easy to find. Mens Wearhouse is near the Millenia mall and also easy to get to. There will be plenty of other local companies as they serve the prom and cruise markets as well as weddings.
Walt Disney World Swan Dolphin have gown and tuxedo rental as part of their package.http://www.swandolphin.com/feedback/wedd��Other than that, I d contact either Walt Disney World or go tohttp://www.mouseweddings.com/weddingadvi��
