Bikini vs Tankini vs One-Piece: How to Choose the Best Swimsuit for Your Daughter

What's the Best Swimsuit for Your Daughter?

Shopping for your daughter's swimsuit can feel surprisingly overwhelming. Walk into any store or scroll through any website and you're immediately faced with a sea of styles — bikinis, tankinis, one-pieces, bandeaus — each promising to be the perfect fit. The truth is, there's no single "best" option. The right choice depends on your daughter's age, how she plans to spend her time in the water, and what makes her feel confident and comfortable. Here's a breakdown of each style to help you shop smarter this summer.

Girls' Bikinis: Bold, Trendy, and Fun

The bikini is the classic two-piece — a shorter top paired with matching bottoms — and it remains one of the most popular swimsuit styles for a reason. For tweens and older girls who love to keep up with fashion, the bikini offers unmatched variety. Prints, colours, and silhouettes change every season, and buying separates means your daughter can mix and match tops and bottoms to create combinations that feel entirely her own.

From a practical standpoint, bikinis are lightweight and quick-drying, which makes them great for beach days and pool parties where she's in and out of the water all day. The trade-off is coverage — a bikini offers less of it than other styles, and it may need a quick adjustment after a particularly active round of wave-jumping. For girls who are more focused on fashion than lap swimming, though, it's hard to beat.

At Limeapple, our top bikini picks include the Rani Embroidered Trim Bikini — our bestselling style, available in White and Turquoise — along with the Izy Crinkle Tie Bikini, which features an adjustable tie closure for a more secure fit, and the Flora Rosette Triangle Bikini, which brings a feminine, standout look to any beach day.

Girls' Tankinis: The Best of Both Worlds

If your daughter loves the convenience of a two-piece but wants a little more coverage than a traditional bikini offers, the tankini is the perfect middle ground. The key difference is the top — instead of a shorter bikini-style cut, a tankini features a longer tank top that sits closer to the hip, providing more coverage through the midsection without sacrificing any of the ease that comes with a two-piece.

This style works particularly well for active swimmers, since the longer top stays put during more vigorous movement. It's also a great solution for girls who fall between sizes, since one-pieces can be tricky to fit when the torso length doesn't line up perfectly. And unlike a one-piece, bathroom breaks are effortless — no peeling off the whole suit mid-afternoon.

The slight downside is that the top can ride up during intense swimming, and for older tweens who want a more fashion-forward look, a tankini can feel slightly less sleek than a bikini. That said, it's one of the most universally flattering and practical styles out there. Our Fay Crinkle Tankini — available in Blue and Fuchsia — is a consistent top seller for exactly that reason.

Girls' One-Piece Swimsuits: Classic, Secure, and Surprisingly Stylish

The one-piece has had a serious style comeback in recent years, and today's options are anything but boring. Modern one-pieces come in bold prints, intricate cutouts, and eye-catching silhouettes that hold their own against any two-piece — which means your daughter doesn't have to sacrifice style for coverage.

For younger girls, toddlers, and active water enthusiasts, the one-piece is hard to beat. It stays in place no matter what — whether she's taking swim lessons, boogie boarding, or racing down a water park slide. There's no adjusting, no shifting, and no worrying. It's also the most practical choice for competitive swimming or any activity where a secure fit matters most.

The main inconvenience is bathroom breaks, which require removing the entire suit, and fitting can be tricky for girls with longer torsos. But for the right child and the right occasion, no other style offers the same combination of security and coverage.

Our standout one-piece picks include the Ester Crinkle One Piece in Fuchsia, the Kaya Crinkle Bow Tie One Piece in Candy Pink, and the Kaya Crinkle Bow Tie One Piece in Blue Stripe — each one built to last through a full summer of adventure.

Bandeau Swimsuits: Worth a Special Mention

The bandeau two-piece occupies its own category and deserves a closer look. A bandeau top is strapless — or comes with removable straps — which gives it a sleeker, more grown-up aesthetic that tweens tend to love. It's a style that feels effortlessly chic without trying too hard.

Our June Crinkle Ruffle Bandeau Two Piece — available in Candy Pink, Black, and Orchid — is one of our most popular styles for older girls. The ruffle detail keeps it playful and feminine while the crinkle fabric adds texture and easy, breezy summer style. It's worth noting that bandeau styles work best for tweens around age 10 and older, since a strapless top needs the right frame to stay comfortably in place.

So, Which Style Is Right for Your Daughter?

The simplest way to decide: think about how she'll actually be wearing it. If she's a fashion-forward tween who wants maximum style options and plans to lounge on the beach, a bikini is the obvious choice. If she wants the flexibility of a two-piece but prefers a bit more coverage for active play, a tankini will serve her better. If she's younger, takes swim lessons, or loves high-energy water activities, a one-piece is the most practical and secure option. And if she's an older tween who wants a sleek, strapless look for beach days and pool parties, a bandeau is worth considering.
