I have several DES-typical characteristics that work in my favour. Poor upper body strength, and un-bulky arm and shoulder muscles. Very little body hair and female pubic hair pattern. A touch of gynecomastia. Not that anyone would care in the real world, but the ratio of my finger lengths is in the female range.
My bone structure works in my favour too. Although I am on the tallish side for a woman (5'8"), I am not tall enough to attract unwanted attention. My hips, while small for a woman, are wide for a male, giving me a plausible figure. I do not have prominent brow ridges. My chin and nose, while larger than average for a woman, are not massive enough to make me want FFS.
My wife is always commenting that clothes look good on me because I am tall enough and slim enough.
