Finding your personal style can be a challenging and laborious work. It requires a lot of time and patience, and knowing what you want. But before, make sure you have the wardrobe essentials. Once you get that out of the way, look for on trend pieces, which will highlight your style.
The white shirt and the jeans are probably the most important wardrobe essentials. You wear them almost everyday, so it's crucial to get the right ones. When it comes to white shirts, there are two things you need to know: a white silk shirt is suitable for any occasion, and second - while shopping, don't avoid the men's section. Buy a white shirt like this one from H&M Man or steal one from your boyfriend.
As for the jeans, they just have to fit and feel comfortable.
The secret of looking sophisticated in a cold rainy (or sunny) day is to have the perfect trench coat. Buy the classic version in beige, because you will never get bored of it. I had mine for almost 5 years now, and it still looks stylish. Find a similar one here.
Cliche or not, the little black dress is a wardrobe must-have. If you want something different, go for a bold version of it in black sequins. Match it with black shoes and a sparkling bracelet, like the one in the picture, which you can find at H&M.
