Up to level 10, all attire can be upgraded without any requirements - the only cost is time. However, to upgrade for levels 11-15, a lesser attire medallion is required; a greater attire medallion is required for each upgrade levels 16-20. The maximum attire level is determined by the level of the respective building: La Cugina's Suite, or the Sky Lounge for Il Cugino. Additionally, attire can be tailored with Slick Stitches to give it an added bonus.
