Fashion check
In Animal Crossing: New Leaf, a Fashion Check is a side-quest in which the player is required by Gracie to dress in a particular style. The player must meet Gracie's requirement by midnight on whatever day she appears at the Event Plaza.
There are a total of ten styles, which include Basic, Cute, Flashy, Historical, Iconic, Ornate, Modern, Rock and Roll, Official, and Sporty. It is mandatory for players to dress in a full outfit or else they will not be accepted. A full outfit includes a shirt, pants, shoes, socks, and an accessory. Players will pass the Fashion Check as long as they wear enough clothes which match the theme and none which clash with the theme.
When players pass the Fashion Check, they are usually rewarded with a piece of furniture or sometimes a rare item or piece of clothing from Gracie's shop, GracieGrace. If players manage to pass the Fashion Check four times, Gracie will open her own shop, GracieGrace, in the players town on the third floor of the T&T Emporium.
