The most common mistakes when buying a swimsuit and how to avoid them

Buying a swimsuit might seem, at first glance, like a simple task. But as soon as you start browsing through the different models, doubts appear: Will this size fit me? Does this cut flatter me? Should I go for blue, or maybe green? The truth is, many small decisions make a big difference when it comes to feeling comfortable and confident at the beach or pool with your new swimsuit.

At Roidal, we have been designing swimsuits and bikinis for real women for over four decades. That’s why we know firsthand the most common mistakes when buying a swimsuit… and how to avoid them. If you’ve ever bought one that ended up forgotten at the bottom of a drawer, keep reading — you’ll want to know this.

Picking the wrong size is probably the most common mistake. Sometimes it’s because we’re in a rush, other times because we’re unsure how the different models fit… But choosing a size that doesn’t properly fit your body can easily turn that bikini into a piece you’ll never wear. A bikini that’s too tight can dig in and feel uncomfortable, while one that’s too loose won’t provide the necessary support — especially if you’re looking for a shaping or slimming swimsuit.

*Our advice: Take your measurements with a tape measure before buying. On the Roidal website, you’ll find a clear, specific size guide tailored to each type of garment. And if you have any doubts, you can always contact our team. Remember, it’s not just about it “fitting”, it’s about flattering you and making you feel your best.

Every woman is different, and the magic of the perfect swimsuit lies in enhancing what you love most about yourself. But often, we make the mistake of being guided only by trends or what we see on social media, without stopping to think about what cut or design actually suits our silhouette best.

For example, if you have an hourglass figure, bikinis with wide straps and high-waisted bottoms can help you visually balance your shape. If you have a straighter figure, a women’s swimsuit with draping or bold prints can add volume where you want it. And if you need extra support for your bust, tops with underwire or pre-formed cups will be your best allies.

At Roidal, we design with exactly this in mind: so you can see and feel your best just as you are.

Fabric quality is one of the factors that most influences the durability and comfort of your swimsuit, but it’s often overlooked. Did you know not all swimsuits are made from the same type of polyamide or elastane? A high-quality fabric not only shapes your figure gently but also withstands chlorine, sea salt, and sun exposure much better.

At Roidal, we use high-quality Italian fabrics, carefully selected for their excellent elasticity, soft touch, and durability. Plus, our new collections,  both Roidal and our youthful line, Tessy,  are crafted in Spain under strict quality control processes. Because a swimsuit shouldn’t last just one summer: it should accompany you year after year, maintaining its shape and vibrant color.

What looks spectacular on the hanger might not look quite right once you try it on. Often, this has everything to do with color. Each skin tone has its best color allies, and knowing yours can help you always make the right choice.

For example, fair skin tones tend to pop with intense colors like electric blue, fuchsia, or vibrant prints. Golden or sun-kissed skin shines beautifully with earthy tones, olive greens, or warm colors like coral. And if you’re lucky enough to have a darker complexion, pastel shades and white create a stunning contrast.

If there’s one thing our years of experience designing swimwear have taught us, it’s that there’s no single perfect body — just infinite ways to highlight the unique beauty of every woman. At Roidal, we work with care and attention to detail to create swimsuits, bikinis, beachwear, and accessories that not only follow the latest trends but also truly meet what you need: quality, style, and comfort.
