Floral Shirts also collectively known as Hawaiian Shirts are a craftable Dress item from the Reign of Giants DLC. It requires 3 Papyrus, 3 Silk, and 5 Cactus Flowers to craft and an Alchemy Engine to prototype. It restores 3.3 Sanity/min and provides 240 points of protection from Overheating while worn.
The Floral Shirt spoils after 15 days similarly to the Fashion Melon and the Garland instead of losing durability as it's worn, thus it cannot be repaired with a Sewing Kit. Storing it into an Insulated Pack or Snow Chester will slow the time it takes to spoil.
Since the item requires Cactus Flowers to be crafted, it cannot be crafted until the first Summer. Unfortunately, it only lasts 12 days after that, because things spoil 25% faster in Summer.
- The Floral Shirt used to be crafted using Petals, Silk, and Butterfly Wings, and it wasn't as effective against heat.
- Even though it requires a Cactus Flower to craft (suggesting that is the flower on the shirt), typical "Hawaiian" shirts depict the Hibiscus, the Hawaiian state flower.
