One of the trickiest things about buying swimwear for a tween or teen is that her body doesn't stay the same for long. A swimsuit that fits perfectly in December can feel tight or awkward by the time the next holiday season rolls around.
That's exactly why TAG•V builds an adjustable tie-back into so many of our styles | it's one of the easiest ways to get truly easily adjustable swimsuits that work as well this year as they will next.
If you've been searching for tween tie-back swimwear or teen tie-back swimwear that won't need replacing every few months, this is the design detail to look for.
What Is a Tie-Back Design?
A tie-back swimsuit has a criss-cross or scoop-neck back that ties into place, rather than a fixed strap sewn to a set length. Instead of one size point, she can loosen or tighten the tie herself to get the fit right, and adjust it again next season as she grows.
Why It Matters for Growing Girls
- It adjusts as she grows | rather than replacing a swimsuit every few months, a tie-back design can flex with small changes in height and shape.
- A more secure, personalised fit | she can tighten it exactly to her comfort level, rather than settling for whatever fit a fixed strap gives her.
- Confidence in the water | a snug, well-adjusted back means less tugging and adjusting mid-swim, so she can focus on actually having fun.
- Longer wear from one swimsuit | a design that adapts season to season means more value from each piece, not less. It's swimwear that grows with her, rather than swimwear she outgrows in a matter of months.
For mums after the perfect swimwear for teens and tweens alike, a tie-back design is one of the simplest ways to future-proof the fit.
Where You'll Find It
TAG•V's Seafoam Sweetie style is one of our most popular tween tie-back designs, using this scoop-neck, criss-cross tie-back, and it's also the silhouette behind Blue Lagoon, Sugar Rush and Blackout from the Sun Drip Collection. Every style pairs the adjustable tie-back with removable age-appropriate inserts and Inclusive Sizing, so the whole fit works together, not just the back. You can see them all in the TAG•V swimsuit collection.
Frequently Asked Questions
How do I know how tight to tie the back?
The tie should feel snug and secure without digging in. A good check is that she can move her arms and shoulders comfortably while the back stays in place.
Can she adjust it herself?
Yes. The tie-back design is simple enough for most tweens and teens to adjust on their own, without needing help every time.
Will the tie-back design last more than one season?
That's exactly what it's designed for. Because the fit isn't fixed, a tie-back swimsuit can often be adjusted to fit comfortably across more than one growth stage.
