There's lots to consider to work out a harmonious outfit. The most important guiding principle is contrast, which gives you lots of individual creative freedom – you can work with colour, pattern, material...even your personality. Ogonsten Yellow is a yellow linen tie with herringbones, which create a semi-solid, slightly striped appearance. If you choose a white-based, checkered shirt, a careful, floral cotton hanky in the purples and a solid, light brown poplin jacket you'll have contrasts in both colour, pattern and material. Use the colour wheel, limit the number of colours and pattern in an outfit to three maximum, and use the neutrals black, grey and brown when you need to calm down the ensemble, and to keep it classy. Happy experimenting!
