The Diving Girl and the suit that changed bathing to swimming — American swimwear since 1916.

Jantzen
Re-checked daily
Jantzen is an American swimwear brand established in 1916 in Portland, Oregon — famous for the "Diving Girl" logo and a rib-stitch suit that, as its tagline put it, "changed bathing to swimming."

The story begins at the Portland Knitting Company, founded in 1910 by Carl Christian Jantzen and the Zehntbauer brothers. Asked to make warm rowing trunks for a Portland rowing-club member, they developed the elastic rib-stitch fabric that became the prototype for the 1915 swimsuit. The brand name eventually replaced the company's own.

The Diving Girl — designed by Frank and Florenz Clark — first appeared in advertising in 1920 and on suits in 1923, becoming one of the longest-lived apparel icons in the world; by 1932 Jantzen was reportedly the seventh best-known trademark on earth. Ownership later passed through Blue Bell, VF Corporation and Perry Ellis International, and in 2019 to Jantzen Brands Corporation.

Jantzen shopping FAQ

Is Jantzen swimwear good quality and worth it?+

Jantzen is one of the oldest names in swimwear, and that longevity says something about how its suits have held up over the decades. The brand made its name on flattering, comfortable one-piece silhouettes, so it tends to suit shoppers who want a classic, dependable swimsuit over a trend-led one. Judge fit and fabric on the specific style you are eyeing, and you will usually find a suit built to last a few seasons.

What is the Jantzen Diving Girl logo?+

The Diving Girl is Jantzen's signature emblem: a young woman in a red one-piece swimsuit and bathing hat, caught mid-dive with outstretched arms and an arched back. The image became famous around the world in the early twentieth century and remains one of the longest-lived apparel icons there is. Spotting that little red figure is the quickest way to recognise the brand.

Who designed the Jantzen Diving Girl and how has she changed?+

The Diving Girl was designed by Frank and Florenz Clark and first appeared in advertisements in 1920, then on Jantzen swimming suits in 1923. Over the years her stockings and stocking cap were dropped, the suit became strapless in the late 1940s, and the whole design was modernised again in the 1980s. She has evolved with fashion while staying instantly recognisable.

When and where was Jantzen founded?+

Jantzen is a swimwear brand established in 1916 that first appeared in Portland, Oregon. Its roots reach back even further, to the Portland Knitting Company founded in January 1910 by Carl Christian Jantzen and brothers John A. and C. Roy Zehntbauer. The brand name eventually replaced that of the parent company that made the products.

What does 'the suit that changed bathing to swimming' mean?+

That tagline captures Jantzen's role in reframing the garment itself. Around 1921 the company began promoting the idea of the swimming suit rather than the old-fashioned "bathing suit", a shift in language it pushed across all its advertising. The earlier rib-stitch, one-piece pure-wool prototype, designed by Carl Jantzen and first produced in 1915, was lighter and better to swim in than what came before.

How does Jantzen compare to a performance brand like Speedo?+

They serve different swimmers. Jantzen built its reputation on fashion-forward, flattering swimwear with classic one-piece styling, where a race-focused brand concentrates on technical, performance-driven suits. If you want a beach-and-poolside suit that flatters, Jantzen is squarely in its lane; for competitive lap swimming you would look to a performance label instead.

Which Jantzen swimsuit should I buy first?+

A classic one-piece is the most natural introduction, since flattering one-piece silhouettes are exactly what the brand has long been known for. A timeless cut in a solid colour is the most versatile starting point and the easiest to wear year after year. From there you can branch into two-piece and separates styles.

How should I care for my Jantzen swimsuit?+

Rinse the suit in cool fresh water after every swim to flush out chlorine and salt, then lay it flat to dry away from direct sun. Avoid wringing it hard or tumble drying, both of which break down the stretch. A little gentle care keeps the fabric and colour looking good for far longer.

Just how famous was the Jantzen brand at its peak?+

Extremely. By 1932, Jantzen was reportedly the seventh most known trademark in the world, helped along by the Diving Girl who leapt from catalogue covers onto billboards and beyond. Few apparel brands have ever reached that level of global recognition. It is a remarkable footnote for a company that started as a small Portland knitting concern.

Who owns Jantzen now?+

Jantzen has passed through several owners: it was purchased by Blue Bell in 1980, which VF Corporation acquired in 1986, then the trademark went to Perry Ellis International in 2002. In 2019 the brand was sold to Jantzen Brands Corporation. Through all those changes, the Diving Girl has stayed at the heart of its identity.

Did Jantzen always make swimwear, or other things too?+

Its origins were broader than swimwear. The founding Portland Knitting Company produced sweaters, woollen hosiery and other knitted goods before the brand became synonymous with swimming suits. In 1995 the company ceased producing menswear to concentrate on women's apparel, returning to its swimwear roots. That focus on women's swim is where the brand sits today.
