Add-On Idea: Convention/Cosplay Theme

I think this is an add-on that would appeal to a lot of fans of The Sims as many gamers also like to cosplay and to indulge in creative hobbies.

It could include:

• a new sewing skill
• a sewing table/machine which would make a great addition to your creative hobby room!
• outfits inspired by generic anime characters (Japanese school uniforms, magical girl outfits, idol themed clothes, super hero costumes, geeky shirts etc) that don't even have to be actual crossovers with other franchises. I mean magical girl outfits for example all have a very clear similar style!
• nerdy decoration objects that include low-key references to other popular franchises (famous quotes etc) or have to do with science
• mannequins and sewing related objects like scissors, ribbons and cloths that could also visually benefit a boutique
• conventions (comic, games, anime and manga themed) as a new kind of social event similar to festivals but in a closed setting
  And the option to decorate your own convention site
• photography spots (Japanese gardens, Steampunk factories, ...) - this would make a lot of empty room that isn't used for anything in the world more interesting
  Sims from the neighbourhood could sometimes randomly show up in small groups at these spots
• maybe a new form of business model that could go well with other gameplay packs, like Cosplay Cafés or Cat Cafés for exmaple
  This would also open up a new mini job form as a waiter/waitress
• maybe a new food art skill where you can produce food that looks cute or pretty or like some sort of fantasy creature
• Comics, action figures and collective figurines as decoration
• more computer, laptop and console skins including big tower computers with more than one screen and rgb
• rgb wall decorations
• elf ears as an accessorie
• maybe some new form of accessoires that are carried for the purpose of cosplay (plastic swords, school bags, wings)
• cosplay wigs and colored contact lenses (this would also open up the opportunity to implement anime-like hairstyles)
• anime, science fiction, fantasy and superheroes inspired posters
• LAN-parties as a new form of party
• more social interactions related to Fantasy/Sci-Fi and books, maybe talking with other Sims about your favorite Fandom and forming groups (also in connection with other Add-Ons; a sewing group, K-Pop dance group or book club for example)
• huge fluffy and round cat/dog plushies and pillows that are either a form of merch or cute
  
  I'd especially love having actual elf ears (or an elf race) and anime hair styles in the game because it would allow me to add some of my OCs or comfort characters to the game <3
  Also I think that some decorative objects related to sewing would really add to my hobby room ingame.
