Jehova's Witness... friendly?

I'm only out to some people at my work and they're totally fine w/ it, but there is an 80 yr old lady, really sweet, whom I work close with who is Jehova's Witness and I was just wondering if one day my "butch" fiance came in my office, if she would see me any different. She's very nice, but way conservative and she seems like she'd be weirded out with me. It's not something that would ruin my day, but I was just wondering on your opinions.
