Alex Marie Tankini | Sophisticated Two-Piece Swimwear
Our Alex Marie tankini redefines two-piece swimwear with thoughtful design that balances coverage and style. The longer tank silhouette skims the midsection while adjustable straps let you customize the fit to your comfort level. We crafted this piece for women who want the flexibility of separates without sacrificing the polished look of a one-piece.






We engineered the Alex Marie tankini using Lycra Xtra Life fiber, a premium blend that resists breakdown from chlorine, sunscreen, and saltwater. Traditional swimwear fabrics lose elasticity after 15–20 swims; this advanced material maintains its compression and recovery for an entire season and beyond.


Fit & Sizing Guidance
The Alex Marie tankini runs true to size with a fitted-but-forgiving cut through the bodice and a slightly relaxed drape at the hem. We recommend ordering your usual dress size; the built-in shelf bra accommodates most bust sizes comfortably, and the adjustable straps let you fine-tune lift and support.
Finding Your Best Length
Our standard length hits mid-hip on most body types, providing coverage without overwhelming petite frames. If you’re between sizes, size up for a longer, more relaxed fit or stay with your usual size for a closer, sportier silhouette. The bottom band sits securely at the natural waistline and won’t ride up during swimming or beach volleyball.

Styling & Versatility
One of the defining advantages of tankini styling is the ability to mix proportions and patterns. The Alex Marie design pairs with high-waisted bottoms for maximum coverage, classic hipster cuts for balanced proportions, or cheeky styles when you want a sportier look. We offer coordinating bottoms in the same fabric and colorways, but the neutral palette also complements solid swim bottoms you may already own.
Layering a lightweight sarong or beach cover-up over the tankini creates an instant resort outfit suitable for poolside dining or casual boardwalk strolls. The longer length means you won’t feel exposed when transitioning from water to lunch, and the tailored neckline looks polished under open cardigans or kimonos.

Questions About the Alex Marie Tankini
Yes, the tankini top is sold separately from swim bottoms, giving you the flexibility to mix sizes and styles. This is especially helpful if you wear different sizes on top and bottom or want to create multiple looks by pairing the tankini with various bottom styles. We offer coordinating bottoms in matching fabrics and prints, as well as solid options that complement the tankini’s color palette.
The tankini hits mid-hip on most body types, providing midsection coverage while maintaining a flattering silhouette. The length skims over the stomach area without clinging or adding bulk. The neckline offers moderate coverage with adjustable straps that let you customize both support and how high or low the top sits. It strikes a balance between full-coverage one-pieces and minimal bikini tops.
The built-in shelf bra with removable soft cups accommodates most bust sizes comfortably, typically up to a D cup. The adjustable straps with non-slip backing allow you to dial in the right amount of lift and support for your frame. If you typically wear DD or larger, you may want to size up one size for additional room through the bust, or consider adding underwire cups for extra support during active swimming.
This tankini is designed for both active water sports and relaxed poolside lounging. The chlorine-resistant Lycra Xtra Life fabric and reinforced stitching at stress points make it durable enough for lap swimming, water aerobics, or beach volleyball. The secure fit and non-slip straps mean you won’t spend time adjusting or worrying about coverage during movement. Many customers wear it for serious swimming sessions as well as casual vacation wear.
Rinse your tankini in cool fresh water immediately after each swim to remove chlorine, salt, and sunscreen. Hand wash with a gentle swimwear-specific detergent and lay flat to dry away from direct sunlight. Never wring, twist, or machine dry the fabric, as heat and agitation can break down the elastic fibers. Store it flat or gently folded rather than hanging by the straps to prevent stretching. With proper care, the Lycra Xtra Life construction will maintain its shape and compression for an entire season and beyond.
The Alex Marie tankini distinguishes itself through premium Lycra Xtra Life fabric that resists chlorine and sun damage far longer than standard swimwear materials. The built-in shelf bra with removable cups and adjustable non-slip straps provides customizable support that many tankinis lack. UPF 50+ sun protection is woven into the fabric itself rather than applied as a coating, so it never washes out. The thoughtful construction details—flatlock stitching, reinforced seams, quick-dry properties—reflect our commitment to creating swimwear that performs as well as it looks.
The Alex Marie tankini runs true to size with a fitted-but-forgiving cut. We recommend ordering your usual dress or swimwear size for the best fit. If you’re between sizes or prefer a more relaxed fit, size up for additional length and a looser drape through the midsection. The adjustable straps allow you to fine-tune the fit regardless of which size you choose, and the four-way stretch fabric adapts to different body shapes comfortably.
