The Number 1 thing to bring is a fun attitude, This shoot is as much for you to express yourself as it is for a gift for your significant other. That aside we suggest a couple things:
A couple of changes of outfits (3 or 4) This is a personal choice, but think about what makes you look good. Some ideas from what women have used for their boudoir photography shoot: a silk nightshirt, jeans and a bra, boy-shorts, work-out outfits, sports jerseys, their mans work outfit, or nothing at all. Adding accessories such as jewelry, gloves, hats, ties and wraps help keep things interesting and gives you something to play with. Other props such as guns (unloaded please), guitars and footballs are also fun. Being creative and personal is the key.
Outfits that we have found to be very flattering are: push-up bras, corsets and boy-shorts. Size is also very important, it is best if your outfits don't hug too tight or create any extra lines on your body, this is common with thigh highs because they need to be tight to stay up, we suggest the ones that are held up with a garter belt. It is best to bring a few options so your shoot will have lots of variety.
