Swimsuit shopping shouldn’t be stressful, especially when the right style can make you feel confident, supported, and totally comfortable. Whether you’re poolside, beach-bound, or just enjoying the sunshine, the most flattering swimsuits for women over 55 are designed to celebrate your shape,not hide it.
We spoke with Katy O’Beirne, Styling Program Manager at Nordstrom’s flagship store in New York City, who works with women of all ages to find flattering, functional fashion. Here’s her expert advice on what swimsuit silhouettes really work and which brands her clients keep coming back for.
1. Look for Strategic Support and Coverage
“Women over 55 often ask for more bust support and a little more coverage around the tummy or rear,” says Katy. “The good news is, brands are finally making stylish suits that offer both without looking matronly.” Silhouettes like surplice wrap one-pieces, tankinis, and swim dresses top her list of flattering go-tos. Look for high backs, built-in bras, and thicker straps for comfort that lasts all day.

2. Fabric Details That Flatter
Ruching is a stylist’s best friend,” Katy shares. “It adds texture, smooths the midsection, and gives the illusion of a more defined waist.” She also recommends power mesh lining and stretch fabrics with shape retention to hold everything in comfortably.
High necklines and adjustable straps can help provide better coverage and fit for different body types, especially for women looking for modest yet modern options.
3. Brands Women Over 55 Keep Buying
“There are definitely a few standout brands that my clients ask for by name,” says Katy. “Miraclesuit, Magicsuit, and Lands’ End are favorites because they balance fashion with fit. They know how to sculpt and smooth without making you feel squeezed.”
These brands use technology like built-in shaping panels and supportive cup designs, which are especially helpful for women with fuller busts or post-menopausal body changes.
4. Modern Features Make a Big Difference
Don’t underestimate the power of adjustable elements. “Things like adjustable straps, convertible tops, and swim bottoms with full rear coverage go a long way in improving comfort and confidence,” Katy says. “It allows the swimsuit to work with your body, not against it.”
Bonus: many brands now offer UPF 50+ protection, so you can protect your skin while enjoying your time outdoors.
5. Fit First, Trends Second
When it comes to what’s “in,” Katy advises clients not to chase every trend. “Find a silhouette that feels great first. Then you can play with color or prints to make it feel current.” She often recommends classic styles in flattering shades like navy, plum, or black, which tend to feel elevated and timeless.
According to a recent YouGov survey, over 65% of women over 50 prioritize comfort and confidence when choosing a swimsuit, more than any specific trend or brand.
