Styling and planning your own shots for a magazine submission does involve some work, you can’t just slop on any old thing, but at the same time, it can be easily done if you have a focus for the shoot. I would plan to pitch and pick a theme that is simple. Some that I love are Accessories, or Swimwear, or hairstyles or shoes. (These are also good for a petite girl.)
Next think of the audience and magazine you will be submitting to.
Usually a fashion magazine will want every thing shot highly stylized. Meaning the fashion items need to current or a seasons to come items. A magazine will show winter pieces in the early fall or late summers. Sometimes swimwear shots are wanted in the winter time to prepare for summer editorials. Usually a fashion magazine will want every thing shot highly stylized. Meaning the fashion items need to current or a seasons to come items. Also higher end magazine usually hire their own photographers and are more in control of what they are wanting. It is easier to submit to a smaller magazine to start, or one with a smaller circulation, a trade magazine, or a weekly lifestyle magazine.
Getting the things you need:
I would pull clothing from designers and try to get in touch with showrooms, to loan you items for the shoot. It is best to first submit some images to the magazine with the photographer and get them at least interested in your work. Then get the styling together.
IDEA: If you are planning to shoot jewelry then stop by some boutiques or email them or ask who you can speak to about loaning you some jewelry for a photo shoot that is being submitted to a magazine.
Getting a Location:
IDEA: offer the location some extra photography needs, they might be more interested in letting you use their location if you give them some nice free shots of the space.
