How Rupa Frontline sizing works
Rupa Frontline uses inch-based sizing (check the brand chart). Measure your snug underbust and standing bust as described in our fit guide, then read your size from the chart below. If you already know your size in another system, convert it first with our size converter.
Good to know: Men\u2019s innerwear sizing; included for reference.
