WTB (Want To Buy) is a standard posting format when seeking to purchase specific items: 'WTB Supreme Box Logo Hoodie size L' clearly communicates what you're looking for. WTB posts appear across resale platforms, forums, and group chats, functioning as reverse listings—instead of sellers posting items, buyers post desires. The format enables finding pieces that aren't actively listed for sale, reaching collectors who might be willing to sell the right price. WTB posts typically specify item, size, colorway, condition preferences, and sometimes budget. Effective WTB posts are specific enough to attract relevant responses without being so narrow that nothing qualifies. The complementary format is WTS (Want To Sell). WTB/WTS conventions standardize community commerce, making transactions easier to initiate. Understanding these formats enables full participation in streetwear's secondary market beyond just browsing existing listings.
