The Size Guide
Well hello!
We know how important it is to choose the right size swimsuit for the mini in your life! So we've put together a comprehensive size guide with detailed measurements.
Our swimsuits, by nature, have a good amount of stretch in them so my advice is that the full height measurement is the most important. If you'd like - you can get a tape measure from the top of your mini's shoulder to their ankle then compare it to our size chart.
If in-between - size up to get the most wear out of your sun suit and if you have any questions at all please email me on holla@cucumber-cool.com
