Which size should I choose?
Finding the right swimwear size online doesn’t need to be a challenge. We’re happy to assist you! Follow these tips to find your perfect MYMARINI fit. And if you still need help, don’t hesitate to reach out.
Smaller in size
If you are between sizes, we recommend choosing the larger size.
Tipps
- Our sizes align with your regular clothing size, but keep in mind that swimwear should fit like a second skin to stay secure in the water.
- Between sizes? Consider your height. For example, if you’re between S and M and are on the taller side, go with size M for extra length.
- Since our swimwear doesn’t use underwires, just stretchy fabric, the material will adapt to your shape.
- Our darker colors (like black or navy) may fit a bit more snugly due to the dyeing process, so you might want to size up if you prefer a more relaxed fit.

How do our styles offer UPF 50+?
Our swimwear provides reliable protection against UV rays. The UPF 50+ rating is achieved solely through the choice of yarns and the dense fabric construction — no additional finishes or chemical treatments are used.
This means the UV protection is built into the structure of the textile itself, so it won’t wash out over time. Plus, all our fabrics are certified according to OEKO-TEX® Standard 100 and the Global Recycled Standard (GRS). A smart blend of functionality and comfort — just as you expect from MYMARINI.

What other customers say
“It fits perfectly. I feel well dressed and supported in all the right areas.“
“The cut is sophisticated – it's cut very well. The back cutout and tie at the back of the neck make this swimsuit something really special. People notice it even early in the morning when I'm swimming laps; people compliment me on it all the time.“
“There’s no slippage in the water; I wear it with shorts or a pareo wrap skirt out of the water. I feel very well dressed. This swimsuit flatters my figure by emphasizing my waist. I have an extremely small bust, so I wear a small insert. This swimsuit holds it in place without slipping.“
“I feel well dressed and protected.“
“It's super comfortable and covers everything, while still looking good. No need to worry about anything slipping out.“
“A well-cut style that provides great support for full busts. It's not run of the mill.“
“It fits well even though I have a very long, narrow torso with a small chest.“
“Fits perfectly when swimming and looks sophisticated from the back.“
“At my age, it’s lovely to have everything elegantly covered. Also great for swimming.“
“An elegant style that fits perfectly.“
