Tips to find the perfect suit:

  • Our suits are designed to fit snug and feel compressive but not crazy tight.
    The elastics shouldn't dig. If they do, try a size up.
  • In-between sizes? Keep the compressive tip in mind. A snug fit in the changing room will give you the best fit in the water. Only size up if you can maintain that compressive fit.
  • Remember that when you're in the water, your suit will relax a tiny bit -- we designed with this in mind.
  • If you have an extra long torso, try a tall version of our one-pieces! Our tall length one-pieces also work great for bigger boobs, to give some more room in the shelf.
  • Bust measurement is your overall bust circumference, taken around the largest part of your chest (not just your bra band size).
  • High-waisted styles sit at your waistline, so size these bottoms to your waist measurement as best as possible. Low rise more your style? Size to your hip measurement.
  • Measure yourself and find the closest match in the chart for your size.

Reviews Summary
Customers say this swim top is comfortable, flattering, and supportive with soft material that stays in place. Many appreciate the stylish cut and quality construction, noting it works well for various activities like surfing and beach volleyball. Common feedback mentions the top runs small, so sizing up is recommended. Some customers wish for more coverage or padding options, particularly those with larger cup sizes. Overall, reviewers praise the fit, durability, and attractive colors, though a few note the higher price point is justified by the quality.

    Super flattering and comfortable

    I don't buy anything but LOF bathing suits anymore and am always asked where my bathing suit is from when I'm wearing them. This new top is great, I like the compression on my chest and its not going anywhere. . This top does run slightly smaller, i bought a large and wear a small/medium in tops.

    I’m a LOF believer now!

    I bought the streamline too in bronze and the hi hi bottom in bronze recently for a vacation at the beach with my family. Packed a few bathing suits, wore this one most of the time. It’s super flattering, comfy, and I feel comfortable chasing around my kids in it. I got a medium and I’m 5’-3” and 125lbs, athletic. Tried my usual small first but felt it was just a little too tight, the medium was perfect.

    Stunning colour and fit

    absolutely love this bathing suit top! The material is super comfortable, and it fits snugly without feeling tight or pinching. I especially love this style because it provides great coverage in both the chest and back, so there’s no spillage and everything feels secure. I am normally a size medium in tops but find with most bathing suits, I need to size up to a large and LBF is no different.
