As the fashions start to change along with the leaves, Rach's buddy Gretta explains how different trends are determined. "A lot of designers go back to get their inspiration," she says. "So they look at vintage clothes and clothes from different eras, and then they take the different looks and bring them forward in a new way. If you love fashion and want to add a little zip of the 'here and now,' then hold on to those extreme pieces because they do come back." For instance, Gretta says the patent leather shoe was fashionable last season, and this season it's back but with a gold touch.

Gretta's Fall Fashion Tips

• The wide pant is back. "It's just another option for people who didn't want to wear skinny pants," Gretta says. "My lesson here is if you do wide on the bottom, you have to do smaller on top."

• Wear narrow belts up high.

• Update your look by adding details. "You can take a basic black dress and embellish it with glue and a little fabric -- it's all about faux fur and feathers this season!" Gretta declares.
