Finding the best swimsuits for a rectangle body shape can be challenging, but it shouldn’t be. We’ve put together our favorite pieces for all the beautiful shapes and sizes our bodies come in.

If you’ve no idea what a rectangle body shape is, firstly, it’s a pretty common one. It’s essentially an overall fairly slim shape with narrow hips and a small bust. So, when it comes to finding the right swimsuit for a rectangle body shape, we’re usually trying to add in some curves and still maintain balance. If you’re looking for advice on styling other shapes, we also have swimwear guides for pear-shaped bodies and an apple body shape.

​Swimwear can be a minefield. What may flatter one body type may even detriment the beautiful natural shape of another body type. When it comes to swimwear, going for high-quality pieces is always worth the price tag. It can be easy to think that it’ll only be worn a few times a year, so spending money on swimwear doesn’t make sense. However, good pieces can last years and years, and classic pieces can really stand the test of time.

How To Choose The Perfect Swimsuit For a Rectangle Body Shape

  1. High leg cut bottoms. This is the best way to elongate the leg and draw attention and create the illusion of wider hips, drawing them out to create an hourglass figure.
  2. Frilly or string bikinis. Again, these will emphasis your bottom half, creating more shape in the overall outfit and the illusion of curves in your body.
  3. Belted one-piece swimsuits. A belt is a good idea as it creates the illusion of a smaller waist, and where one pieces can sometimes skim over your curves, this ensures this doesn’t happen.
  4. Cut out details. Again, sheer or cut out panels help create definition and add some visual interest. These are also great if you don’t want to commit to a two-piece swimsuit but still want to bare some skin.
  1. Square necklines and higher necklines will emphasise the boxy silhouette as opposed to creating the illusion of a fuller upper body.
  2. Bandeau bikini tops will similarly flatten your top half as opposed to adding shape in the bust area.
  3. Ill-fitting swimwear. No one wants a bikini bottom that looks like a soggy diaper, first make sure you’re getting your swimwear in the correct shape.
  4. Boring swimwear. Okay, this might seem like an unreasonable point, but, swimwear without an interesting aspect, either in the design or prints or colors, is likely to have nothing to draw the eye to.

When it comes to swimwear, it’s certainly daunting, especially if you aren’t 100% comfortable with your body type to begin with. The best advice before it comes to any swimwear is to love the skin you’re in and understand that all bodies are beautiful – no matter the shape or size. Change also can’t happen overnight, if this is your first foray into swimwear, you can dip your toe with a one-piece or a high-waisted bikini which provides a bit more coverage.

If you’re still confused or don’t have the patience to do your own swimsuit shopping, we’ve done the work for you! We’ve put together 12 of our favorite swimsuits for a rectangle body shape, to have you feeling like a million dollars!
