Here are more companies for your perusal: - Costumes n partieshttp://rent.costumes-n-parties.com/index.php?route=common/home - Costume City http://www.mycostumecity.com/ There's a whole list of costume rental stores over here: http://www.supermommy.com.sg/costume-shops-halloween/
There is a wide selection at CCM and I find their rental cost reasonable, There's an online album where you can view their costumes and the price but it will be better if you go down personally to their store and try. http://www.ccm.com.sg/
