RTW is an acronym used in retail, fashion, and various online men’s style forums and stands for “Ready To Wear”. RTW refers to clothing that is bought in-store or online and does not require any alterations. Just buy and put in on. In other words, the garment is ready to wear.
In men’s style and women’s fashion, Ready To Wear (RTW) is often used interchangeably with OTR (Off The Rack).
In a strictly menswear context, RTW and OTR can sometimes be construed as pejorative, being the least desirable tier, particularly when it comes to suit options.
