ANSWER:

You’re definitely sinful for what you had done but this does not impact your marriage.

On my wedding day after the nikah i was ignorant to let a man fashion designer sew a headpiece on my hair it wasnt my intent . He saw me without hijab and as much as i fought and wanted my wedding the right way ,i messed up in that aspect.He saw my hair and touched my head before my husband did. Is my marriage VALID?Will Allah forgive me.? I feel humiliated and ashamed. I want to cry.
