It's a nice design, but the children's sizes come up very small and the company has a "no returns" policy so we're stuck with a tiny swimsuit that's we can't use. The UK size age 10-11 is also marked as an Australian size age 8-10, so I think the Australian sizing is more accurate. The "detailed size chart" that they claim means you can't accidentally order the wrong size consists of a waist measurement and did not give us an accurate sizing result. This is a bizarre policy for an online only company.
