Make sure you are wearing age appropriate styles. It is a very common problem to wear styles that are really designed for very young women in the prime of their sexual appeal by older TG women just discovering women's fashion. The general tendency is to dress in a younger style than is probably optimal for age and presentation but most seem to recalibrate their sense of fashion as the novelty wears off and they acquire a personal sense of style and preferences.
Kendra makes a key point--constantly and carefully study other women. Learn their mannerisms, behaviors, roles, and style.
I find it really helpful to study the roles of women in old movies. In the 40's-60's, the roles are dated and were sometimes exaggerated to our post-modern eye, but the underpinnings are the same in most cases. Study Bogart and Bacall. Others have cited the scene from "The Year of Living Dangerously" where Segourney Weaver and Mel Gibson meet in the open air cafe and are caught in the rain as a laboratory for the study of feminine gestures.
