I really like the cut, colours, soft feel of the material and especially the style of Instant Swim suits. Although I think I might be between sizes as I purchased a size 10 but the straps are too loose for training. I will try size smaller next time.
Fits well and feels secure, lovely colour. Great purchase, would buy from here again!
the fit is amazing and its perfect for swimming, I will buy again for sure
So good, really flattering
it’s so beautiful. my only note is that it does gape slightly at the front because i have A cup boobs and it’s got a little extra fabric/touching for if you have boobs. but still fits well
Great !!! I live in Costa Rica. My swinsuit Traveled from UK to Costa Rica ! Wow
I'm absolutely in love with this swimsuit! As a beginner I wanted something that is functional but also makes me feel good wearing it and this piece definitely checks all of the boxes. The color is gorgeous and the fit is great. I chose to with the smaller size as I'm kinda in between sizes and I'm very happy with that choice — feels very comfortable in the pool. Definitely recommend!
Practical, comfortable and really flattering swimwear. Nice fabric even for someone who is allergic to almost everything. Definitely going to purchase more in the future!
Badpak zit perfect!
Love the material - a snap bit small
I love this bathing suit!
Absolutely love! The open back makes it feel super stylish whilst being supportive for athletic swimming! I’ll take one in every colour please!!🥰
Perfect fit and shape! I really enjoy wearing it during my swimming training sessions and in competitions!
I can do miles with this suite! Best swim suite I owned so far 💜
Super nice and beautiful. True to size :)
It had my first swim in my Instant Swimsuit yesterday and it was very comfortable to swim in. It hugged my body nicely while I did my laps. I sized down to have a snug fit. For reference, I’m typical 32 in Jolyn but I ordered 30 in Instant Swim and it fits perfectly. I have my eyes on the Matcha now, will definitely order more.
Love this suit and colour wave!
I have looked for a one-piece FOREVER and I have gotten so many compliments on this one! I am 1.62cm/60kg and ordered a Size M.
The colour of this piece is gorgeous and the material feels really good quality. However, I really wanted to love it more than I do. I don’t know if it’s a sizing issue or just my body shape, but I can’t wear this to swim as it causes so much drag because the front gapes open so much when I swim. I’ve tried to include a photo to demonstrate. It ends up flapping open in the water, especially when I move fast, that I start to worry my chest is exposed as that’s what it feels like.
Love the swimsuit, great fabrics and sizing.
Very comfortable even after swimming twice a week for months!
Gorgeous suit! I would say if you are between sizes or ordering based on your usual clothing size, consider your torso/belly area more. I went with my usual size which is more based on hips/thighs etc. but wish I sized down. The suit fit when I tried it on but was too loose to swim comfortably in, so if you’re unsure I would definitely size down. I sewed the straps under to shorten them and it is perfect now. Recommend!
Getting into actually swimming for the first time since childhood as I get ready for a triathlon, and honestly, this bathing suit made me feel so much more comfortable getting into the pool. It feels and looks great! I will say it does ride up the back a bit, but it's not really any issue in the pool. I probably wouldn't wear this casually for lounging on the beach because of that, but that's not why I bought it. For context, I'm 6'1'' (and got the long in large) so that might have something to do with it. Also worth noting that the color is lighter in person than it appears in the pictures, so it's more slate colored than black. Still lovely though!
Absolutely love this swim suit! The design is so flattering. As slightly heavy chested, I feel secure in this suit but the straps and sides don’t feel tight or dig into my skin like other brands. I love the colour (my favourite), and when I’m swimming it feels comfortable. 10/10.
Great quality and style! Love it and felt super confident in it can’t wait to get more colors!
Very lovely swimsuit. You can feel the quality of the material!
Perfectly fits. Coliur is stunning. Love it !
Love it! The fit is so great and feels awesome for training. I’m 5’9 but with long legs and think I could have done without the long size.
Lovely swimsuit - comfortable and flattering fit. I’ll be getting more.
Totally in love with the swimsuit! It looks amazing, the fit is amazing and the quality of the fabric is great.
I love this!! So flattering and the most gorgeous material! Lovely to have a costume that’s suitable for lengths but also looks good!
Absolutely love this suit! It is hands down the most flattering training suit I have ever worn, and all while still being so supportive and keeping the girls in place! lol. Will definitely be ordering more colors.
Perfect for training, comfortable durable and looks amazing! Making you feel good in and out of the water.
Love this suit! The blue is so flattering, and the fit is excellent! Snug in the right places but still super comfortable. The fabric feels high-quality, and stays put all day with no adjusting.
Bough for my daughter as a Christmas present & is a keen swimmer but it got its first Christmas se in a Scottish loch on Christmas Day🎄🥶
Love the fit, really flattering! Also the quality is really nice, it feels like it will not vanish quickly.
The fit is so lovely in these, I love the high leg and the criss cross straps look so good! The double lining means it doesn’t wear out either :)
Comfortable and great coverage.
Took this swimsuit on the swim camp and it didn’t disappoint, I love the fit, colour everything! already been added to my rotation of swimsuits
I’m 5”8 and definitely need the tall, fits well for swims but doesn’t feel too sporty if I’m at a beach / sauna too.
