How to Find the Best Nani Suit for Your Cup Size

Finding the perfect swimsuit shouldn’t feel complicated—especially when you’re trying to match your cup size to the right amount of support, comfort, and coverage. At Nani, every suit is designed to move with you, adventure with you, and make you feel confident in your own skin. But different cup sizes and body types call for different levels of structure and stretch, so here’s your expanded guide to choosing the best fit.

Our Favorite Styles by Bust Size & Body Type

A–B Cup: Light + Active Support

If you want a suit that keeps up without feeling bulky, this is your sweet spot. Smaller busts can thrive in flexible, sporty silhouettes that focus on comfort and movement.

What to look for:

• Crop tops + sporty designs

• Removable pads so you can customize your shape

• Compression or 4-way stretch fabrics that won’t gap or slip

Best Nani Picks: Reversibles — lightweight, flexible, and perfect for an active day outside.

C Cup: Balanced Support + Coverage

C cups fall right in the middle, meaning you can lean sporty or structured depending on your adventure. This size needs a little bit of everything—support, shape, and reliable coverage.

What to look for:

• Medium-wide straps that stay put

• Supportive bands so you’re not adjusting all day

• A silhouette that feels secure but still flattering

Best Nani Pick: Avant Crop — supportive, minimal, and made to move.

D–DD Cup: High Support + Stay-Put Features

For fuller busts, support is key—especially when you’re running, jumping, cliff-diving, or chasing kiddos at the beach. You want lift without sacrificing comfort or range of motion.

What to look for:

• Wide straps that won’t dig into shoulders

• Compression support (Nani’s specialty)

• Full-coverage fronts for secure movement

• Thicker bands for extra stability

Best Nani Picks:

• Cut Back Crop — our fan-favorite for a reason

• Supportive One-Pieces with built-in structure

DDD–F Cup: Maximum Support + Confidence

For the fullest bust sizes, the right design is everything. Look for suits built intentionally for comfort, stability, and a confident fit that stays put through every adventure.

What to look for:

• High-coverage tops with structured support

• Extra-wide straps for shoulder comfort

• Longline or thick supportive bands

• Sports-bra-inspired fits that hold everything in place

Best Nani Picks:

• High Tankinis

• Full-Support Tops

• Anything featuring wide straps + compression materials

Our Favorite Styles by Body Type

For Larger Busts:

Cut Back Crop
Our best-selling top for a reason. The racerback strap offers secure, all-day comfort, and the double band provides reliable support—think of it like your favorite sports bra, but built for swim and adventure. Highly recommended for fuller busts.

For Smaller Busts:

Switch V Crop / Twist V Crop
A flattering V-neckline with carefully placed seams creates shape and highlights natural curves. Designed with a slightly lower neckline, this silhouette offers a subtle lift while keeping everything comfortable and streamlined.

Quick Fit Tips for Every Size

No matter your cup size, these tips help you find a suit that truly fits:

• Jump. Twist. Reach. If it stays put, it’s a winner.

• Check your straps. Racerbacks = no slipping, especially during activity.

• Coverage = freedom. It’s not about hiding—it’s about moving confidently.

• Between sizes? Size up in tops for more comfort + secure support.
