Asking Question is very simple in seeing but it covers many issues and aspect which is hidden from our eyes. The simple answer in one word, you should wear "Ihram" in Umrah. What is Ihram? Ihram is not a simple dress that can be worn with taking a normal bath in a bathing tub like you wear a dress before going to any party. It is a spiritual dress that covers your body and soul. It is also called a uniform to perform Umrah. Every field has a unique uniform in our world like a judge's uniform represent a "Justice" and a white overcoat is an identity of a "Doctor". Samely two unstitched sheets of fabric is an Ihram. How is beautiful our religion than the others? Our religion never gives us permission to cross the boundaries even we are in the House of Creator. But the teaching of other religions do not secure women during religious activities like Islam. Islam gives a different law for men and women in the shape of Ihram. Women are not required to wear two unsewn sheets rather they can wear normal dress such as they wear in homes.
No. That would be some Orthodox Jewish women. Not Muslim women.
