When it comes to swimsuit tops, the right fit is everything.
Your swim top should flatter and support your bust, keeping you comfortable and confident all day long. Whether you’re after something flirty or functional (or both), we’ve curated our favorite Helen Jon tops by bust size to help you find your perfect match.
Not sure where to begin? Start with your general cup size, then explore the styles that suit you best. If you need to measure, see our measuring guide below.**
Helen Jon Swim Top Sizing:
o XS: A/B cup (32.5 - 33.5 inch bust)
o S: B/C cup (34.5 - 35.5 inch bust)
o M: B/C cup (36.5 - 37.5 inch bust)
o L: C/D cup (38.5 - 39.5 inch bust)
o XL: D/DD cup (40.5 - 42 inch bust)
Smaller bust…
Smaller busts don’t typically need as much built-in support, which means you can lean into fun, shape-enhancing details. Ruching, ruffles, and textured fabrics create a naturally flattering silhouette for A to B cups.
Try:
o String Bikini Top — A timeless favorite with light coverage and adjustable ties. Feminine, flirty, and one of our best swimsuit tops for small busts.
o Ruffled Shirred Cross Over Bra — Ruffles and shirring add subtle volume and visual interest, plus this includes removable push-up cups.
o Over-The-Shoulder String Top — With eye-catching trim and thin straps, this minimalist style is anything but boring.
Medium bust…
A medium bust often benefits from a blend of lift and flexibility. Think supportive bands, adjustable straps, and molded cups — styles that offer support for B to C cups without feeling restrictive.
Try:
o Banded Bikini Top — This sporty chic bikini top features a supportive band and adjustable fit, ideal for active beach days.
o Hook Back Tortoise Bandeau — This strapless top has sewn-in molded cups and elegant tortoise detailing for subtle support.
o Twist Front Bralette — The twist-front detail enhances your shape while the wider straps offer all-day comfort.
Fuller bust…
Fuller busts call for extra structure — but that doesn’t mean compromising on style. Prioritize tops with molded cups, hidden underwire, adjustable features, and designs created specifically for D to DD cup sizes.
Try:
o Tortoise Halter — This classic halter has wide ties at the neck and back to ensure the perfect fit.
o Twist Underwire Bra — With molded cups and an adjustable slider back, this bikini top offers a customizable fit you’ll feel great in.
One Last Tip
Your ideal top might change depending on your plans for the day. Styles with less coverage are great for lounging, while full-support styles shine when you’re swimming, staying active, or chasing littles in the waves. And this holds true regardless of your bust size.
