Match the setting first
For a workday, think about walking and what the bag must carry. For an evening, the amount you need may be smaller. Start with function, then consider whether the shapes sit well together.
Compare visual weight
A compact shoulder bag can balance a fuller trouser leg, while a structured tote may echo a tailored jacket. These are options to try, not rules that override fit and comfort.
Keep color choices simple
Repeat one tone or choose a controlled contrast. View product colors in reliable light when possible, since screens can show color differently.
