Question: I am enquiring about the white wedding dress in terms of its resemblance to the [white] suit of the men, [particularly since I am] not [going to be] wearing white gloves nor white shoes with it; [So] what is it's ruling?
Response: It is permissible for a woman to wear [a] white [dress]. There is no prohibition regarding the wearing of a white dress, with the condition that it is feminine in design and does not resemble [the clothes of] the men and nor the disbelievers; Rather, that which is prohibited is for it to be worn in a manner in which it resembles the men, due to that which has been related on the authority of Abu Hurayrah رضي الله عنه who said:
"The Messenger of Allaah ﷺ cursed the man who wears the clothing of the woman, and [likewise] cursed the woman who wears the clothing of the man" [transmitted by Abu Daawood no.4098; graded saheeh by al-Albaanee].
And likewise if there was any resemblance to the disbelievers, then that is certainly not acceptable.
And Allaah [alone] has the Complete knowledge [of all affairs].
