Fall even more in love with the sea: our feature on cute, grown-up swimwear and beach items

When you have a trip to the sea coming up, you may find yourself wondering, “What swimsuit should I wear?”

As we get older, we may feel more self-conscious about our figure or showing skin, but these days there is a wide range of designs that are both cute and flattering.

From high-waisted styles that slim the tummy area to one-piece swimsuits that bring out your femininity, the right choice can give you a style you feel truly confident in.

Add beach items such as a cap or tote bag, and you have a cute, grown-up outfit that looks great both by the sea and in town.

Here, we share tips on choosing swimwear and apparel to make your ideal time at the sea come true.

Stylishly Flatter Your Figure: Tips for Choosing Cute Swimwear for Grown-Up Women

“Putting on a swimsuit somehow makes me nervous…” Most of us have felt this at least once. Areas like the upper arms and tummy tend to bother us more as we get older. But lately, many “cute swimsuits” have appeared that flatter your figure while bringing out your personality.

Here, we introduce designs perfect for grown-up women, by type.

Just the right coverage with a relaxed feel: the reassuring “tankini”

The “tankini” combines a “tank top” and a “bikini.” With a camisole-style top and bikini bottoms, it is perfect if you prefer to show less skin around the waist. It covers the tummy while being a two-piece, so it is easy to move in and easy to change.

Today there are plenty of feminine designs, giving you a stylish look both at the sea and in town.

Feminine with less exposure: the classic “one-piece”

If you want to keep skin exposure to a minimum, we recommend the classic one-piece. Because it covers the tummy, it is very flattering, so you can enjoy your beach time with peace of mind.

Recently, more styles feature subtle yet highly designed details, such as creative cutouts on the back. The key is enjoying the balance of not just “covering up” but also “showing off.”

Recommended for lovers of simplicity: the beautifully shaped “high-waist”

If you want a more flattering silhouette, high-waisted designs are also effective. By emphasizing the narrowest part of your waist, they naturally make your legs look longer.

They have a vintage-like feel and create a simple yet distinctive style. They are perfect for anyone who thinks, “I don’t like anything too flashy, but ordinary swimsuits are boring.”

Keeping in mind not just “covering up” but “showing off in a balanced way” gives you a much more refined look.

Stand Out at the Beach: How to Create a Cute, Grown-Up Beach Look

To make your favorite swimsuit look even better, the trick is to think about “an outfit that shines at the sea.” The key lies in the perfect balance of “glamorous without being too revealing” and “functional yet cute.”

Add an effortless touch with a rash guard: stylish sun protection

An essential for beach style is a rash guard that doubles as sun protection. This versatile item protects your skin from UV rays while balancing your outfit.

UMMY rash guards dry quickly even when wet, and simply throwing one on gives your beach style an effortless, polished look. With an even more stylish design, they are activewear for grown-ups that works both at the sea and in town.

Accent with “color and material” for photogenic looks

Choosing colors makes your time at the sea even more dramatic. Colors that pop on the beach, like translucent emerald green or orange reminiscent of a sunset, are enough to make your heart flutter on their own.

Wearing a vivid orange in a sporty way is also a trend this year. On the other hand, choosing calm colors such as muted pink or sand beige gives an elegant, soft impression. Both blend well with mature skin, and under natural light they make your look even cuter.

“Stylish and easy to move in” is the grown-up answer

At the sea, you move around more than you might expect: walking on the sand, standing up and sitting down. Not just looks, but ease of movement and comfort are important too.

UMMY swimwear is designed to fit Japanese body types, so it stays in place as you move and offers a comfortable fit. It is designed with a focus on “staying comfortable all the time,” both in the water and on the sand.

What UMMY proposes is not just a swimsuit, but a 2 mm thick “bikini-cut wetsuit.” It has the light look of a swimsuit while offering the warmth and protection unique to wetsuits.

Because it is designed to fit Japanese body types, it stays in place even when you move actively, giving you a “comfortable feeling of security that lasts,” both in the water and on the sand.

Make Beach Time Even More Comfortable: A List of Stylish, Handy Items to Bring

Relaxing on the sand or taking a break at a café — to enjoy these moments smartly, choosing the right accessories is essential.

Make the strong sun your ally: a cap to protect your face

At the beach, a cap that combines sun protection and style is a must-have item. A simple design goes with any swimsuit and makes a great accent for your outfit.

The UMMY washed cap features the natural texture of 100% cotton. Just putting it on gives you a relaxed look that blends naturally not only into the beach but also into strolling around town.

Worry-free even when wet: a tote bag to carry your things

Sunscreen, towels, drinks… you tend to bring more to the beach than you expect. That is when a sturdy canvas tote comes in handy.

The UMMY canvas tote bag is made of a material that stands up to sea breeze and sand and gains character the more you use it. The larger size fits a beach towel, while the smaller size is great for cafés and shopping.

Protect your valuables: a waterproof, dustproof hard case

For storing valuables you want to bring but don’t want to get wet, like your smartphone or accessories, a waterproof and dustproof case is a must.

The UMMY “HAKOBUNE” hard case is a serious waterproof, dustproof and shockproof hard case that meets the IP67 standard. It is designed to float on water, so you can relax even if you drop it. Inside is customizable foam that firmly protects sunglasses, cameras and smartphones.

Meaning “a box that floats on water,” “HAKOBUNE” is beach gear for grown-ups that combines design and functionality.
