Establish the main colours first
A purple top and cream wide-leg trousers already make a distinct combination. A black blazer places a darker frame around them. Begin with those three pieces before introducing more colours. Look at the purple beside the trousers in daylight; warmer and cooler versions can create different effects. You do not need a colour-type category to decide. What matters is which version you enjoy and which pieces you would want to wear again. A simple smooth top hem is usually easier to arrange beneath the blazer than several overlapping edges.
Keep the wide trousers movable
Try the trousers with the intended shoes before deciding on the hem length. Wide legs can move more during walking than they appear to when you stand still. Turn, step up and sit down. The hem should not slip beneath the shoe during these movements. Pale shoes can continue the cream colour area, but they are not essential. If you alternate between flats and higher shoes, test both. Trousers do not need to work identically with every heel height; it is more useful to establish one reliable combination for your plans.
Leave the second accent optional
An orange bag can deliberately stand out beside purple. If two strong colours feel like too much, begin with a black or pale bag instead. This is a choice rather than an exercise in being daring. With a small bag, check that your phone and keys fit without significantly distorting its shape. For a longer day, the top should remain comfortable without the blazer. Finally, sit in the complete outfit so the waistband, top hem and blazer do not press over one another. This keeps the colour combination practical as well as visually clear.
