You could study style for years, and still have scope to learn more. It’s an interesting topic that doesn’t always get the love it deserves, with some dismissing it as frivolous. We wear clothes everyday (although a duvet day now and then is compulsory), and wearing something you love can often change your mood. In homage to the dynasty that is style, this A-Z guide will bring you a little insider information on one of our favourite subjects, this week concentrating on all things U. UGG UGG boots are pretty much a love or hate trend, there's no room for middle ground here. A couple of years ago, the popularity of the slipper like boots reached staggering heights of popularity. It has to be said that they're extremely comfortable and they look great teamed with jeans and a cosy jumper. The UGG range includes bags, clothing, outerwear, hats, gloves so there's plenty of options if you're a fan of the brand. Una and Aoife Belle Foden are UGG fans Underwear as Outerwear Wearing underwear as outerwear is a popular fashion trend thanks to celebrities such as Kim Kardashian and Rihanna. It doesn't have to be completely risqué but bralet tops and slinky lace separates are everywhere. When styled the right way, it's a trend that can look great, but it can go the opposite way too. If going down this route, stick to clean lines and neutral colours. Don't overcomplicate it.
