Portraits can either be intimate or within a group setting. To me, it allows me to be personal with you, allowing you to shine and be the star. What do you think of when you hear the term "portrait"?
Now this! Is way more than sex and lingerie. Yes, those things are tied into the genre but overall, boudoir is intimacy, sexiness, confidence and all the above. It can be as simple as a t-shirt and undies, lingerie or full-blown birthday suit.
