I think it depends on the context.  The establishment and honestly your age.  When I was 18 and shopping at Victoria's Secret, it was pretty tacky.  Now I'm an adult shopping for a dress to wear to a wedding.... yeah, I'm going to bring my husband in so he can help me with zippers and snaps and help me pick a good dress.  No one has cared.  But also.... I wouldn't bring him into a "Women's" dressing room.  Seems disrespectful to the shy or modest women in the other stalls.

I am such a hypocrite because I was just reading your comment and thinking "yeah damn right, I wouldn't want men in the women's changing rooms" then remembered the other day when I went in a men's shop, got mens jeans and tried them on in the mens changing rooms
