Swimwear sizing in Australia is genuinely confusing. A size 12 in one brand fits completely differently to a size 12 in another, and with teens growing fast, last summer’s suit often doesn’t make it to Christmas. Before you guess and hope for the best, here’s how to actually get it right. We’ve been fitting Aussie girls aged 8 to 16 at Salty Ink Designs for years, and this is what we tell every parent who asks.
Why Sizing Matters More Than You Think
A suit that doesn’t fit is a problem the moment she hits the water. Bikini tops that gap, bottoms that move around, one-pieces that pull at the shoulders none of that is comfortable, and teens notice it more than they let on. Getting Teen Girls Swimwear that actually fits her body, not just her age, makes the whole beach day easier for everyone. Grab a soft tape measure before you buy anything. It takes two minutes and saves a return trip.
How to Measure for the Perfect Fit
Three numbers are all you need. Whether you’re shopping Swimwear Perth or ordering online for Swimwear Brisbane delivery, these measurements cut out the guesswork:
- Chest: Around the fullest part, tape snug but not tight. This is the most important measurement for bikini tops and one-pieces.
- Waist: About 2–3 cm above the belly button, at the natural waistline.
- Hips: Around the fullest part of the hips and seat, roughly 20 cm below the waist.
Cross-reference those numbers against the Salty Ink Designs size chart rather than going by age. When the measurements sit between two sizes, go up. The fabrics have good stretch, and a slightly roomier fit holds up better through a full day of swimming.
Choosing the Right Style for Your Daughter
Once the measurements are sorted, it comes down to what she actually wants to wear and what works for how she spends her time in the water.
Bikinis and Crop Sets
For girls who want current styles without the fuss, a bikini set works well. The Teen Girls Swimwear bikini range at Salty Ink Designs runs in sizes 8 to 16, with adjustable straps and waistbands that actually stay put when she’s active. Look for lined fabric and proper closures; these matter more as girls get older and want a fit that doesn’t shift mid-swim.
Long Sleeve Surfsuits for Sun Protection
Australia’s UV is serious year-round, not just in the middle of January. Even on overcast days in Perth or Brisbane, UV levels regularly hit dangerous levels. A girls surfsuit long sleeve Australia rated UPF 50+ is the most practical option for kids who spend long stretches in the water. Our long sleeve surfsuits use chlorine-resistant fabric with flatlock seams, so there’s no chafing on a full day of surfing or snorkelling. The coverage suits girls who prefer not to layer a rashie over a separate swimsuit, and the fabric moves properly rather than dragging.
Period Swimwear for Teens
We get asked about this more than almost anything else, and it’s worth knowing about. Period swimwear Australia has a built-in absorbent liner that handles light-to-moderate flow in the water, no pads, no tampons, nothing bulky. Girls in the 10–16 age group who’ve just started their periods can swim and surf without sitting it out. If this is something your daughter needs, it’s worth including alongside your usual Teen Girls Swimwear picks when you’re ordering for summer.
Quick Care Tips to Make Your Swimwear Last
The fit is one thing. How long the suit holds that fit is another. Salt and chlorine both degrade the elastane fast if you skip the rinse. Here’s what works:
- Rinse in cold fresh water straight after every swim. Every single time, not just sometimes.
- Hand wash with mild detergent. The washing machine is too rough on the stretch fibres and shortens the life of the suit.
- Dry flat in the shade. Direct sun fades the print and breaks down the fabric, and the dryer does the same.
- Don’t wring it. Press the water out gently with a towel instead.
