Don't think it was about you at all . She had to be changed to go back on stage , this was the area she was given to change in , so she did it .

Maybe she’s just not a prude and doesn’t give two shits what ANYONE thinks. Each to their own.

She maybe testing you. You have to watch more than she just undressing. Does she look at you when she does it?

Women are known for teasing and not giving you anything to leave you starved and frustrated. They do it naturally. Men are direct, the are problem solvers.

She was comfortable and needed to get dressed.

I would not take it as either a compliment nor an insult. I don't think it had anything to do with you. Some people are pretty casual about brief nudity when there's a purpose for it. I suspect that if you continue in theater you'll encounter these situations again.

Your First play?
Most actors learn pretty quickly having hangups about their body is not conducive to quick costume changes.
Having to change with the opposite sex happens a lot in the theater world.

It's a dressing room... Your presence is irrelevant...

Some young women are very comfortable with their bodies, and are pragmatic about a professional space...I wouldn’t take it as an insult, more like a compliment that you could be trusted.

None of them, she's just pragmatic and open minded.

And in the end-I'm safe. had a nice conversation with her about Xmas while a bi cast member helped her dress.

In Italy and other parts of Europe it is not unusual for men and women to change in and out of swimwear righjt on the beach.

if you have to think about it that much it is your problem not hers....

Most likely an exhibitionist. When has age stopped a horny guy? She is IMO a "prick teaser" as well!

In Theatres this is normal like unisex washrooms, it is all about respecting ones space and relizing it is not about YOU ,Just older generation who have not really beome completly comfortable about nudity or semi nudity it bothers as they do not know how to react ,when it is simple you do not react and just go about doing your own thing like they are not there

Every decade we age, we become invisible to another decade of women, unless you have a butt load of money.

Actors learn to be comfortable around other actors, like teammates in a locker room. This kind of story is typical in the world of theater, in particular. Don't read too much into it one way or the other.

Maybe she wanted you to "hit" on her? Who knows, some younger women are highly attracted to older men.

How about a little bit of both, and the fact she's an actress.

Another rehearsal and this time she left and found an empty hallway to change in when there were two younger guys (her age) in the room. Back to square one...

After many years as a nudist, I've learned at a very deep level that nudity is not sexuality, and vice versa. In fact, sometimes nudity can put up a slight barrier when you're interested in getting to know somebody better. But not always.
