Absolutely love this swimsuit. I brought a size M(32), and it is a little tight around the crotch area. I am a curvier UK size 12 so would recommend sizing up if you have slightly wider hips. The colour is beautiful and stays put during a long swim, would highly recommend! The order was despatched and delivered quickly, I can't wait to purchase my next one.

This swimsuit is my all time favorite! It fits perfectly in all the right places and is light and easy to swim laps with. Would definitely buy again and again!

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.

This is my third swimsuit from Instant Swim (it’s getting out of hand!) Always super comfortable and flattering. I love this colour way, I’ve had a lot of people ask where it’s from!

I was surprised how supportive this swimsuit is. Comfortable to swim in and stays in place. I ordered a 32 to ensure enough length in the body as I would normally order a tall.

Bought my first one during my first pregnancy and it’s so flattering I love it so much, had messaged the instagram page for advice on size and they were so helpful can’t wait to get more colours

This swimsuit is amazing. It fits me perfectly and feels very flattering. For reference, I’m 5'5", 125 pounds, with a 34C bra size and the size M was just right. Highly recommend!

Absolutely love the swimsuit!! Was nervous it wouldn’t be supporting enough for swimming but I did a 1km PB on my first swim!! So happy I’m going to order another one

I’ve been ocean swimming for 5 years now and could never find a one piece to suit my shape however this one has blown me away. I also purchased the Ferrari red & black and get comments from random strangers asking me where I purchased it from. It’s so comfortable, the material and cut are second to none and perfect for swimming distance in the hot Australian summer and all year round. Highly recommend!

Thanks for creating a one piece that actually feels fun and cute rather than stuffy! I really enjoyed wearing it on my recent holiday -
it gives you a better tan than most swimsuits!

The most versatile swimmer. I wear mine for swim training, surfing, a dip in the ocean and a sunbathe on the beach. I just love how comfy and flattering they are. I immediately need to buy more in different colours for my summer wardrobe.

Very good quality and excellent fitting. However, I think the sizing can be very tricky because it really depends on your body shape, structure. First, I ordered an S because it is my usual size but in the breast it was very loose that’s why I’ve exchanged it to XS which holds me tight but in the water it is perfect. For reference I am 160 cm, 56 kg.
The customer service is excellent, the communication was very easy with them. :)

Adore this swimsuit!!! Fits perfectly - tight but isn't restrictive and it is so flattering! Have stopped reaching for any of my other swimsuits so will for sure be getting more colours.

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!

I wasn't sure how the top would fit the girls, but it keeps them secure during training without feeling restrictive. Love this bikini so much, I got the set in a different colour!

Alice H.Verified
Really like mine! Looks great and you can actually swim properly in it. I was between a M and an L and got L, I think next time I’d go M as when it’s wet it is very slightly baggy on me, but I am planning on getting another one :)

This is my second time buying this bikini. The only reason I had to replace it after 1.5 years of use is because I lost it! The fabric held up perfectly despite frequent wear, and it’s great for swimming. On top of that, it looks amazing and works just as well for lounging on the beach. Highly recommend!

Gorgeous soft towel which gives you that perfect cosy feeling after a long set. This was a great staple in my training bag while training in Spain.
Gorgous bright colours that don’t fade after washing, simply perfect for training and sunbathing!

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.

This is the best swimsuit in terms of quality, fit, style, flattering-ness, I’ve ever worn- put it on and instantly pulled up the website to order another color! I’m 5’9 and got a 30 tall and it fits perfectly

I’m tall, and this is the first swimsuit that doesn’t feel like it’s trying to saw me in half. I swim outdoors a lot, and the back is perfect—finally, tan lines that don’t look like a geometry experiment. Love it!

My new favourite swimsuit! I get compliments wherever I swim wearing this one!
It’s so comfortable, the colour is gorgeous, the back detail is stunning, I’m literally in love 💚

Love the fit and feel of the swimsuit. I'm a bit short (5'3) with a short torso and went for a size 30 as its my usual size but as its a cheeky suit, i might have even gone smaller tbh. I've used it for both sea swims & pool lap swimming and it holds up very well.

Obsessed doesn’t even cut it. Goggles are IMPOSSIBLE to find and I’ve put up with a leaky pair for a year. These stick to my face without the band round my head which is when you know you’ve hit gold!! Super padded and comfy, don’t crush my face and don’t leak!!! A perfect everyday goggle

The nicest swimsuit I own!! I absolutely love everything about it - the fit, shape and how nice it feels on! As someone who spends hours in the pool each week, this makes it a lot better!

Lisa O.Verified
What can I say, it looks great, it feels great, it is great. I measured myself and compared other brands' size guide that I already have to this one to make sure I get the size right and I did. Also, the size gallery was incredibly helpful. Cannot recommend this item enough!

Finally found a swimming costume that I don't need to size up to get the length I need! Love having the regular and tall options and it's so comfortable and flattering on

I am absolutely in love with this swimming costume! It looks exactly like it does on the website. Colour is beautiful, fabric is so comfy and flattering. Super functional for competitive swimming, it keeps everything feeling tucked in and aerodynamic. I have quite a long torso and the tall size definitely makes me feel more comfortable. OBSESSED! 🩵🩵

This is honestly the most beautiful and flattering swimsuit I’ve ever owned. It fits like a dream, feels super comfortable, and gives such a great shape. I feel amazing in it — buying it in more colors for sure! 🩷

Kailee C.Verified
I am honestly obsessed. It’s so flattering, fits perfectly, and I love that it’s still practical for a long swim training session but also works for the beach! If you’re in between sizes you can size up - I think this fits slightly smaller than the Karma style and it’s relatively adjustable with the tie. So happy with it!

I honestly love instant swim, this is my second swimsuit I knew after trying the first it would be an staple swimsuit for me for training, spa, recovery and was just waiting to justify buying another in a different colour. The costume just hugs in all the right places, the material is super sculpting, soft and just amazing quality. Having been a swimmer for almost 20 years, since I was 4 years old I have always struggled with finding swimming costumes that don’t dig in and make my body feel like...

My first Instant Swim swimming costume and I'm obsessed! So comfy, secure, amazing quality, and I love the colour! And really can tell the difference in feeling more streamlined than lots of other costumes and helping me swim faster, finally got my mile under 30 minutes and I'm giving credit to Instant Swim!

I am so pleased with the purchase. This is the best swimsuit I have ever had. It ticks all the boxes - long torso, right colour, excellent cut, really well made. Who ever made it new really well what was doing! This is exactly what I need - great quality and simple but not simple. Thank you very much. Plan to buy one more for someone 6ft2 - as tall as I am.

Love this colour way!! Very girly, has definitely motivated me to get to the pool more. Waiting for the Matcha to restock in my size so I can buy that one too <3

Absolutely LOVE this swimsuit! I’m 5’11 and an athletic build (a wide back), and I’ve always struggled to find a swimsuit that fits and is comfortable.
The fabric is so lovely, it was so comfortable in the pool, and it’s really flattering.
I definitely recommend it!

I wanted to love this swimsuit & after finally getting my size right, I absolutely do! The colour, the fit, the swim... all totally lush... the compliments are an added bonus! I will definitely be re purchasing when Matcha comes back!

Klaudia R.Verified
Love this suit, so flattering on!! And really comfortable, great for training! The fabric is quite thick, and it hugs just in the right places. For reference I’m quite tall, 5’11, and I was contemplating between size tall XS or tall S. I usually wear uk size 8 in clothes, and I’m between sizes when it comes to xs-s, but I’m glad I went for a tall XS in this suit at the end, as it fits like a glove! Definitely needed the extra length tho!!! So I’m really happy this brand comes in tall sizes. High...

Love the color and the fit. I might go one size down next time because I have small boobs and it felt a bit big. I would like it to fit tighter around my chest.
But the suit is very flattering!
