T&T Emporium is the fifth, and final, upgrade to the Nookling Stores, with it becoming available after spending at least 100,000 at Nook Bros. and the store needs to be open for at least 30 days. Additionally, the player needs to complete four fashion checks for Gracie at a satisfactory level.
There are a total of 3 floors for T&T Emporium. The first floor is the Gardening Store, although it has some new items, like Fertilizer and Bamboo. The second floor has furniture and a few other things. The third floor has items from Gracie's collection; these items are expensive and not available elsewhere.
