Someone suggested a dash of Nature Wives and I've got you covered! But I'll add in a long story short, too!
You see, the boutique is actually the only living establishment in this pretty damaged mall. It used to be really big and really crowded until a major fight took place within it, trashing the mall's center beyond work and making every owner freak out and leave.
On the outer skirts and less damaged places of the mall was this boutique/clothing brand called the Shroom and Loom, which was once owned by Shubble's mom until the whole thing. The outter skirts of the mall was then rendered safe and turned into a strip mall of sorts, but no one bought a place there.
Of course, Until Shubble took up the old boutique and roped Scott into business with her! They needed a lot of work and help, but a few friends and new people found their post about it.
One of them was someone named Katherine.
Katherine helped a lot with some funding and decoration, especially with a few flowers and helping choose some opening designs for the place! Strange, most of them are from Shelby's side of the book.
And just as strangely, Shelby gives Katherine a personally-made dress for helping out so much.
