Sizing
Finding the right size is key to feeling great in your underwear. Because our styles are low-rise, we recommend using your hip measurement rather than your waist.
📏 Size Conversion Chart
| Size | Hips (cm) | Hips (in) | Waist (cm) | Waist (in) | EU Pants Size |
|---|---|---|---|---|---|
| S | 81–85 | 32–33 | 70–74 | 27–29 | 38 |
| M | 85–89 | 34–35 | 74–78 | 29–31 | 40 |
| L | 89–94 | 35–37 | 78–83 | 31–33 | 42–44 |
| XL | 94–99 | 37–39 | 83–88 | 33–35 | 44–46 |
| XXL | 99–104 | 39–41 | 88–93 | 35–37 | 46–48 |
Our underwear is low-rise and designed to sit on the hips. For best fit, measure around the fullest part of your hips and check your EU pants size as a guideline.
PetitQ fits close to the body. If you are between sizes or prefer a more relaxed fit, we recommend sizing up.
👙 Special Fit Notes
- Pouches are designed to enhance your shape.
- Some styles are more minimal or daring — check photos and descriptions carefully.
- Bamboo and modal fabrics stretch more than nylon, which can affect fit.
