Clothing changes are welcome and encouraged.  Base the amount of changes on the style you are looking for within your shoot.  Time is an important factor as well.  We are on a limited schedule so the changes need to be quick!  Have a backup plan outfit.  You never know when that favorite shirt you were planning to wear might decide to grow legs and run away....be prepared for anything.  Keep the weather and season in mind when making your clothing selections.  A few tips to guide in the selection process...avoid stripes, solids and bright colors photograph well, patterns work well against solid backgrounds, bring shoes that reflect your personality and change them with each outfit, short skirts and dresses are a big NO NO, accessories like scarves, jewelry and hats always add to the scene, school sportswear works well too.  Girls should wear a cami for quick on the spot shirt changes.
