Help with my wedding dress choice and personal problem?

I have the same problem. When I shave it actually looks like there is hair still there, when its just dark armpits. Over the years, I have learned to accept it. I don't have money like some of the celebrities where they can pay to have their arm pits bleached. I don't think you should feel insecure, I mean I don't think at your wedding your arms will be in the air all day?? Also you can try looking for a gown that has mesh arms, if that is an option.
