First, here's a Firefighter outfit.:

Next up, here's the Parka, which is meant for the Ice Rune Guy:

After that, we have the Hazmat set, which could be useful at the Slime Factory.:

Next up, here's the chef outfit. Insert Gordon Ramsay spazzing out here:

Here's an explorer outfit for both the "historial" researcher (I like to think the typo makes it look like Eliatopia's education system sucks) and the Stalagmite's drop pool:

Okay, now we get to the GOOD ambient outfits (like the Hockey and Football sets were back when Teplar Village was new). Here's the Rambo set because why not? People are probably gonna want something Rambo-related in there.:

And here's the Mafia set, which works for the shady people at the Alion City Hotel:

So yeah, there's that. These outfits, while not useful to players, will help enhance the ambience of the game a little. Yep.
Oh, and here's an outfit and hairstyle for a Guy Fieri parody because why not?:

Mhmm.
