Maybe we think that it makes decorating easier, and giving it a name helps us know where to begin when we are feeling a little lost. Whatever the reason, I think that style is a very elusive entity, something that can take a lifetime to grow. But, for those days when we just can't wait, there are a few easy ways to figure it all out.
One of the simplest, is to take a look at your favorite clothes and accessories. Write down some words that truly describe your personal style, and use the exact same words to find items for your home. eg. classic, eclectic, polished, comfortable, modern, simple, bright/shiny, fitted, vintage etc.
Another idea is to look around your home at what you already have; what do you enjoy, and what do you wish you didn't have? Do you prefer easy-to-clean surfaces, copious collections, a large or small television, squishy or straight-backed sofa's, familiar or original art, rustic or modern, carpets, tile, linoleum or hardwood, chandeliers, lamps or recessed lights. Be honest with yourself, keep what you love, and don't worry about what other people may think.
If you're still not sure, take a few moments to think about your ideal home, and how you would want it to feel. This isn't a pipe-dream, and it may not be your current reality, but it will help you to create your own design inspiration.
