How to Measure for Girls Underwear
To take measurements for girls’ underwear, use a gentle measuring tape and follow these simple steps:
- Waist measurement: Measure at the natural waistline where the underwear naturally sits.
- Keep tape snug: Hold the tape snug but not tight against the body.
- Record measurements: Note the measurement in inches for future reference.
Apply these measurements with the girls’ underwear size chart to get the perfect fit. Plan B simplifies measuring with our easy-to-use size guide.
Tips for the Perfect Fit
Getting the right fit guarantees comfort and confidence for your child. Below are essential tips to keep in mind:
- Size up if in between sizes: Choose the larger size if your child falls between sizes to accommodate growth spurts, which are common during childhood.
- Pick quality waistbands: Go for Plan B girls’ underwear with soft, stretchy elastic waistbands for a snug, comfortable fit.
- Choose stretchy materials: Stretchy fabrics are flexible and ideal for fast-growing children.
- Always refer to the chart: Check our girls underwear size chart by age to make the best choice.
