How can a boy look like a believable girl?

To quote the courses from the Mistress of the Master Mistresses, Miss Vera: It takes skills in cosmetology, deportment, corsetry, elocution and, of course, female flirtatiousness. You also might want to develop a backstory and a more feminized taste in music (and probably the rest of the arts). But, although I do this business fairly well, being born with this as my natural state, Miss Vera can teach you better, so hie thee to her website: Whereupon lies the online presence of the world's first and only crossdressing academy.
