What is the period that should separate one Umrah from another in a state of Ihram, and is it permissible to perform a second Umrah in regular clothes after the first Umrah within 25 days?

There is no specific time interval legislated between one 'Umrah and another, and the preponderant opinion permits repeating it within the same year. Males, when entering into the state of Ihram for 'Umrah or Hajj, must remove tailored clothing and wear the izar and rida, because one in Ihram is prohibited from wearing clothing that is tailored to the body. This ruling applies specifically to males, not females.
