How to measure yourself correctly for choosing a swimsuit

Choosing a swimsuit isn’t only about style, colour or what’s trending - it’s first and foremost about the right fit. Even the most beautiful design can fall flat if it’s too tight or, on the contrary, too loose. Knowing how to take your measurements properly is especially important when shopping online. Done correctly, measurements help you choose a swimsuit that highlights your shape and ensures all-day comfort.

Before you start, prepare a soft measuring tape. It’s best to take measurements in light underwear or without clothing so fabric doesn’t distort the results. Stand upright, but naturally - don’t pull your stomach in or force your shoulders back. A swimsuit should fit your everyday posture, not an artificially adjusted one. Ideally, measure in front of a mirror so you can check the tape is positioned correctly and avoid twisting it.

One of the key measurements is the bust. Place the tape measure horizontally around the fullest part of your chest. It should sit snugly against the body without digging in. Take the measurement on a relaxed exhale. If you’re choosing a style with cups or underwires, it’s also important to measure your underbust. The tape should run straight and parallel to the floor, just beneath the bust. This measurement directly affects support and comfort in the top.

The next important measurement is the waist. To find it accurately, locate the narrowest part of your torso - usually just above the navel. If it’s not obvious, try bending slightly to one side; the natural crease marks your waistline. The tape should lie flat against the skin, fitting closely without squeezing or creating folds. This measurement is particularly important when choosing one-piece swimsuits or high-waisted styles.

Hip measurement is just as essential. Measure around the fullest part of your hips and bottom, with your feet together. Keep the tape level and straight. Mistakes here often lead to discomfort: a size that’s too small may dig in, while one that’s too large can wrinkle and fail to stay in place.

When choosing a one-piece swimsuit, it’s also worth considering your torso length. Measure from your shoulder, down over the bust and through the crotch, to the same point on your back. The tape should follow the natural contours of your body. This helps prevent pulling at the shoulders or discomfort in the lower part of the swimsuit - particularly important if you’re taller.

It’s important to take measurements carefully and repeat them if needed. Don’t rely solely on old swimsuits, as fabric stretches and changes shape over time. Always check the specific size guide of the brand, as sizing can vary.

Accurate measurements take just a few minutes but greatly improve your chances of finding the right fit. A swimsuit chosen with the correct measurements will feel comfortable, enhance your proportions and help you feel confident, whether you’re at the beach or by the pool.
