How to measure girls bra size
Finding her first bra should feel simple, not stressful. This guide is here to help you choose the right size with confidence.
Sassh bras are sized based on the underbust measurement. They are designed to be flexible, with adjustable straps and soft underbands. If the size isn't quite right, we offer free size exchanges for Australian orders, so you can shop with confidence.
How to Measure
1. Measure underbust
Holding a soft tape measure horizontally, pull it all the way around the ribcage just below the chest (also known as the underbust). The tape measure should feel snug
2. No tape measure?
Grab a string (or even a shoelace), a pen and a ruler. Pull the string around the ribcage horizontally just below the chest, similar to using a tape measure. Use the pen to mark where one end of the string meets the other side. Then, lay the string on a flat surface and use a ruler to determine the underbust measurement.
3. Find the bra size
Use the underbust measurement from step 1 to find the bra size on the size chart below. If the measurement falls between sizes on the chart, opt for the larger size. A slightly larger bra will be more comfortable than a bra that's too tight
