Cosplay Taken to a New Level

The concept here is a new technology. A bodysuit, that when you wear it changes your body to take on a form of your choosing until you choose to disable it. It has a number of uses but here we are focusing on one particular use of it, being used by certain groups to fulfill their fantasies. The idea is to focus on specific settings, conventions, clubs etc. Where many people meet, appearing as fictional characters. Unsurprisingly a number people use it to fill out intimate fantasies as well. Sometimes two people meet at random, sometimes two (or more) people agree to take certain forms and then they meet. The conventions may even have discreet areas that are actually intended for such things.

The transformations are complete. While it can not give magic/super powers or anything like that, visually and in voice you become a perfect match of your chosen individual. It can even turn a woman into a man or man into a woman, change height, etc. It can match non-human characters to a limited degree (things like unusual skin colors, pointed ears, horns, tails, fur/scales, things like that. Though it can not give some unrealistic sizes or non-humanoid shapes). Unless you are meeting someone who you pre-planned something with, it is impossible to know who someone is under the disguise.

These could be MxF or FxF couples (under the disguises it could be boy and girl, two girls or two boys, though there will be no MxM content either way). There may or may not be content with one or both in their true forms here. Ultimately the idea here is a Rule 34 story, with some story, but people only pretending to be the actual characters. It could be more casual or develop into actual relationships.  The tags are a list of things I am pen for, they are optional though and it isn't a complete list either.
