One way I know pineapples will always be in style in some capacity is the popularity of luau parties. Not everyone can go on a Hawaiian vacation, but anyone can have a little luau in their backyard, decorated with colorful pineapple plates and tchotchkes like these.
My favorite is this marble and wood pineapple cutting board. Among all the other items, it's so classy and timeless, perfect for any type of party, not just a luau. I found this impressive spread at Sur La Table.
