Why isn't Wardrobe Styling a part of Businesses and Hobbies.

I do know that in Get Famous there is that platform that Sims can stand on to get their wardrobe styled.

I had trouble with getting Sims to buy clothes at a Small Business clothing store using Businesses and Hobbies. There is no option there for styling clothes.

Sorry that I don't know the name of that specific platform from Get Famous. But I did try that out as a lecture of sorts (since there is no wardrobe styling in Businesses and Hobbies, I had to use something else for my Sims to teach on the whiteboard). But that and getting customer Sims onto that platform to try on clothes did work in getting that business some money.

So, why isn't trying on a new wardrobe or getting customers to try on a new wardrobe an option in Businesses and Hobbies?
