Can a Woman Perform Umrah Without an Abaya?

When preparing to perform Umrah, many women wonder, "Can a woman perform Umrah without an abaya?" There is a common belief that wearing an abaya, a long, loose-fitting dress seen in many Muslim countries, is necessary to look modest during Hajj. But in reality, this idea comes more from culture than religion. Islam teaches women to dress modestly, but it does not say that they must wear a specific garment like the Abaya.
