In need of modern clothes!

[MayorAqua]

I was time traveling and happened to catch Gracie in my plaza! The problem is the theme is modern! My closet is full of sporty clothes,AND NOT A SINGLE MODERN ITEM. Please help! Also I found something weird. If I quit without saving,go to the plaza,Gracie will not be there. If I go to any store on main street,then she appears. Weird,eh? Anyway,HELP!!
