- Measure your child’s current swimsuit by laying it flat. All measurements are taken with the garment lying flat, not stretched.
-
Take key measurements.
- One-piece: measure from the top of the shoulder to the crotch, and across the bust and hips.
- Two-piece: measure across the bust, waist, and hips.
- Compare with our size chart. The chart shows the garment’s flat (unstretched) measurements. Our premium fabric comfortably stretches 2–4 cm when worn for the perfect fit.
- Allow for natural variation. As each style is unique, please allow 1–2 cm difference between designs.
- Use age as a general guide. Olga Valentine sizes follow Australian standard children’s sizing, which usually aligns with age — though fit may vary depending on your child’s proportions. When in doubt, we recommend sizing up for extra length or coverage.
