This one for example. Transvestigating is an informal term given to when people play detective and try to determine if a given person (usually a woman) is transgender or not from how they look e.g. photos.
I've seen it more than a few times on Twitter anytime a woman who is tall or muscular or "masculine looking" appears. Quite often, women are wrongly mistaken for being trans.
As well as being transphobic, IMO this harms all women and reinforces stereotypes of what men/women should look like. And the idea of obsessing over people's appearances like this just doesn't sit well with me.
