Identify Your Natural Body Shape

First, it's helpful to identify your natural body shape, which is largely determined by your underlying bone structure. To do this, consider the width of your shoulders, waist and hips, as well as your overall proportions. There are five main shapes:

  • Rectangle: Your shoulders, waist and hips are a similar width, with little definition at the waist.
  • Triangle or "pear": Your hips are wider than your shoulders, with a defined waist.
  • Inverted triangle: Your shoulders are wider than your hips, often with a straight waist.
  • Hourglass: Your shoulders and hips are similar in width with a very defined waist.
  • Apple: You carry more weight around your middle with slim legs.

Remember, this isn't about weight or size. It's about your beautiful, natural build. Women of all shapes and sizes can be equally healthy and attractive. The goal is understanding your body so you can find swimwear that highlights your favorite features and makes you feel your best.

Once you know your shape, you can start shopping strategically. First up, rectangle figures.

One last note: Wearing the "wrong" swimsuit won't ruin your vacation or your life. Let go of rigid fashion rules and wear what makes you feel like a million bucks, whether that's a string bikini, a wetsuit, or something in between. Your body is perfect exactly as it is and deserves to soak up the sun.

So get out there and enjoy the warm weather. Cannonball into crystal clear water. Lounge on colorful beach towels with a book in hand. Chase down the ice cream truck and eat your cone before it melts. When you have a swimsuit you love, you're free to savor all the joys of summer. Happy swimming!
