1. Wear Tried and True: Newer does not equal better. Careening to procure the allure of a new wardrobe could end in a photographed fashion fatality. Opting for a strong and experienced ensemble, allows you to capture a true memory rather than an unfavorable illusion. Shopping your closet captures you rather than a trend. Find everything you can in your existing wardrobe, then go shopping where needed to fill in gaps.
2. Blend Don't Match: Don't waste time, money, or creativity in mirroring a single static hue. Blending color harmonies offers rich dimensional results (and more flexibility in your ensemble choices-see tip 1 above). Try to repeat every color at least twice in your family ensembles and ensure that the hues share a similar heritage (ie jewel tones, pastels, or earthy autumnals). But beyond that, experiment with unexpected color combinations.
Finally forget about saying cheese. Think about a pretty pair of shoes instead. You want to emanate natural bliss and footwear has a much higher chance of precipitating felicity than fermented dairy.
