What is the difference between a kurta and a kameez in Indian fashion?

The terms kurta and kameez are often used interchangeably in common Indian usage, but they have traditional distinctions:

Kurta: Traditionally a collarless or mandarin-collar top, longer in length (typically knee-length or longer), with side slits (chaak) at the hem. Worn by both men and women. Associated with traditional Indian and South Asian dress.

Kameez: From Persian/Urdu origin, meaning "shirt." In Indian fashion context, kameez often refers to the top portion of a salwar kameez suit — could have various collar styles, and is typically styled as part of a 3-piece suit with salwar and dupatta.

In wholesale trade: Both terms are used loosely and interchangeably. "Kurti" is the modern, shorter (knee to thigh length) version popular in current wholesale market. "Kameez" typically implies the longer, suit-appropriate version.
