Satisfied customer
"Suit definitely runs small so ordered one size up and it more than fits. The inner panel seems a bit thicker than usual but after a few times of wearing, I am now used to it. Seems well made and durable."
Exactly what I was looking for
"I loved the fit and the look! Very comfortable"
Looks cute but not functional
"I want to love this swimsuit since it looks so cute. But for DD cup, the design doesn’t hold up after one use! One side starts to sag leaving uneven front and horribly lopsided tan lines!"
"Gorgeous fit and beautifully made. Worth every penny!"
Oceanus One Piece
"Great fit. Flattering for a not-so-perfect body."
Tropical vibes
"I love this suit! They’ve grown fit is perfect. The tropical colors are wonderful for summer vibes. You’ll love it too!"
"Fits smaller than advertised"
Loved it!!!
"I bought an Oceanus style last year after having worn the Sanibel style for ages and I really liked the fit. I bought this one due to the great price and it fits amazingly well. This will be my go to style from now on. I am in my sixties and I have been buying the Miraclesuit brand for over 25 years. They are made well and are a comfortable fit. You can’t go wrong with this brand. I just wish that the price was more affordable."
Beautiful Bathingsuit
"This is a really beautiful bathing suit. It is well made and fits perfectly. I love the vibrant colors. I really like that the straps are adjustable."
Q&A
- Need plus size
- Please check out the link below to find the plus size Oceanus https://www.miraclesuit.com/products/miraclesuit-plus-size-must-haves-oceanus-one-piece-swimsuit?_pos=7&_psq=oceanus&_ss=e&_v=1.0
- Does the solid black oceanus bathing suit in size 14 have adjustable straps? It says it does in the details but when I received it the straps were fixed.
- It has been offered with fixed straps in most seasons, and we've also made it with adjustable straps. Therefore, our inventory is mixed at the moment for the 2026 swim season.
- Is the Malachite color more green or actually teal? Looks green in picture but several reviews mention teal color.
- The Malachite is a green
- not sure if I should order an 8 or 10. I am a size 6 dress but usually buy a size 10 in a bathing suit.
