Fit & Size Guide

UPRO illustration showing how to measure the natural waist and the fullest part of the hips with a tape measure.

Start with your measurements

Use a flexible measuring tape and stand naturally. Keep the tape level and comfortably against your body, without pulling it tight.

Waist: Measure around your natural waist, keeping the tape horizontal.

Hips: Measure around the fullest part of your hips and seat, with your feet together.

Write down both measurements and the unit you used, such as centimetres or inches.

Read the measurement method

Body measurements and garment measurements are different. Check which method the product information uses before comparing it with your own measurements.

If you are measuring an item you already own, lay it flat without stretching it and record exactly where and how you measured it.

Choose for the specific item

Use the measurements and sizing information for the individual product. A letter size alone does not describe a garment's dimensions.

Find the chart for your chosen style

Choose a cut below, open the product, then expand Size guide in its description. Keep the chart open while selecting your size. The links lead to the actual UPRO items, with their available colours, photos and size recommendations.

Cut Examples to compare
Swim briefs Sailor Stripe · Bird of Paradise Print
Square-cut swim trunks American Stripe
Underwear Ribbed Brief · Striped Boxer Brief

Read the size chart before selecting

  • When a chart is labelled as a height/weight recommendation, compare your height and weight with its row and column. It is not a flat garment measurement.
  • Check the units beside waist measurements. 1 inch = 2.54 cm.
  • XXL and 2XL are alternative labels for the same size. A dash means the chart provides no recommendation for that combination.

If your measurements fall between ranges, contact UPRO with the product name, your height, weight and waist measurement before ordering.
