Well, sad to say I qualify to answer your question.

In my opinion dancers of any age should do their utmost to look glamorous in costume and stay in shape. Being out of shape at 20 is not any more attractive than at 60. As we "mature" (and my friends will hear the tone of voice I use when I say that word), it takes more effort to maintain the same body weight, stamina, and feelings of self-confidence but it is worth the effort. And, despite all the effort we put into it, our bodies change (thanks a lot gravity) in many ways that we cannot impact without surgery or some drastic measures. Naturally, there are some people who are genetically blessed and will look good no matter their age and then there are those like me who always have to work really hard to convey the allure of a dancer. Also, with passing time some of us lose the ability to do some moves that we used to perform with no problem. It is not easy then to compete with younger dancers and we have to face the fact that most people who are looking for a performer are more interested in looks than in dance ability (again, this is my opinion formed by my experiences). In my case I prefer to work in venues where skill is valued more highly than superficial appearance.

Regardless of what other people might say or think, I will continue to dance as long as I am able to physically and will look for (or make it if I have to) costuming that is flattering to my body. If no one wants to hire me then I will dance in front of the mirror at home or at some of the workshop haflas that are very welcoming to all dancers.
