Why sizing differs by country, how fabric decides care, and the basics of colour combination.
The same 'M' means different measurements in Korean, US, European and Japanese systems. Shoes are worse still, with mm, US, UK and EU scales all in circulation. For cross-border orders, work from the brand's published measurement table and compare it against a garment you already know fits.
How long a garment lasts is largely decided at the wash. Cotton tolerates water but shrinks, wool deforms under agitation and heat, and synthetics are easy to care for but heat-sensitive. Care symbols are internationally standardised, so reading the label prevents most accidents.
Colour combination looks like pure instinct but rests on simple rules. Colours near each other on the wheel read calm and coherent; opposites create strong contrast. Building an outfit in neutrals with a single accent colour is the lowest-risk approach, and matching tone often matters more than matching hue.
