TTS

TTS (True To Size) is a term used to describe how accurately a garment fits compared to standard sizing. When an item is described as TTS, it means it fits as expected for that size—not smaller or larger than the size on the label.

This info is really helpful when shopping second-hand online where you can't try things on before buying. For example, if you normally wear a UK size 10 on the high street and a seller describes their vintage jacket as "TTS UK 10," you can expect it to fit like your other size 10 items.

That said, it's good to remember that sizing can be all over the place between different brands and decades (vintage clothing is often smaller), so always check measurements when they're provided. Sellers might say things like "TTS for the brand" or "TTS for vintage" to give you more context.

The opposite terms would be "runs small" (meaning you should go up a size) or "runs large" (meaning you should go down a size). These descriptions are super important for making good choices when shopping for pre-loved fashion.
