Choosing the right swimwear after age 50 involves more than just deciding between a bikini or a one-piece, according to stylist Shane Watson. Factors like cut, color, and print can significantly influence how flattering a swimsuit appears.

Watson suggests avoiding plunge-front swimsuits that evoke a "glamorous party wear" aesthetic, citing Kate Moss's recent choice as an example. Styles to steer clear of in this category include those with slashed fronts, gold hardware, glossy finishes, lace-up details, or belts. Instead, she recommends sporty and fresh designs, such as those with a broderie trim, in bold colors like lacquer red.

For bikinis, a well-covered style is advised for elegance and flattery. The ideal option should offer ample coverage for the bottom and sides. High-waisted bikini bottoms with adjustable ruched sides are presented as a suitable alternative, with some styles featuring built-in tummy control. Watson notes that excessively high-waisted bottoms can draw undue attention to the abdominal area, recommending fold-over styles as a more adaptable choice.

The tankini is described as the "worst offender" in swimwear, lacking the smooth line of a one-piece and risking exposure of the stomach if the top rides up. A sleek one-piece is suggested as a superior alternative, capable of smoothing the silhouette. Halter-tie styles are highlighted as a current favorite for their shaping qualities.

Regarding fabric and design, ruched-front styles are noted for their association with disguising the midriff, but can sometimes appear "mumsy." A strong weave that offers containment is recommended instead. Tummy-control features in textured swimsuits are also presented as a way to achieve a smooth silhouette.

Color choices also play a role, with royal blue and tropical brights being listed as potentially aging. Instead, chic and anti-aging colors include black, brown, olive, khaki, red, and black and white. Prints, particularly busy floral patterns, are also flagged as potentially increasing perceived age. Smaller checks or stripes are suggested as more flattering alternatives.

Finally, the leg cut of swimwear is discussed. Low-cut legs can shorten the appearance of the legs and add perceived age. Illusion styles, such as those with contrasting colored leg panels or cross-back designs, can provide the look of a higher leg while maintaining more coverage.
