1. First start off by getting rid of old clothes that have not been worn in a while, and that realistically probably never will be. You can sell them and use the cash towards shopping for some new things, or else donating is a great way to help others.
2. Bring in items that you like but don't know what to match with or want to make a new outfit using. You can ask a personal shopper what they think would go well with it, and try on multiple outfits all based around this one key item.
3. Go online and get inspiration from store sites. You can look at what the retailers put together for looks on the models online and transfer that to your own look using similar items that you already have.
4. Small accessories are a great way to vamp up something you already have. For example, take a little black dress that you've worn before and just looks plain to you now, and add to it. Something like a colored belt or statement jewelry can liven the dress.
5. Future thought: when shopping think about if what you are looking at is a one season item that is going to be out of style almost right after being in vs a forever look that can be taken from season to season. Having a versatile piece that's classy can last a lifetime!
