At Jalayimiya Swim, we use Australian standard sizing, but we understand that sizing differences across brands and regions can be confusing. Below is a detailed breakdown to help you find the best fit for your swimwear.

Core Collection Sizing
We’ve reverted back to true-to-size standard clothing measurements, aligning with other Australian retailers. This ensures a more accurate and consistent fit, giving you confidence in your purchase.
✔ True to Size: All Core Collection pieces follow standard Australian sizing.
✔ No need to size up or down—simply select your usual size for the best fit.
