Customer photo review of Karma Onepiece - Graphite

Carolina V.Verified

SO flattering! I don’t think a swimsuit has ever made me feel this good. I’ve been wearing it for swim sessions and it’s the absolute best which means I’ll be able to both wear it for training and for leisure. Couldn’t recommend enough. For reference, I got the 30 (S) - I’m normally a 36 and could have gone for the 32 (M) so if you’re in between sizes maybe size up!

It was been a while since I bought it but I didn’t really have a chance to wear it. It fits me well outside of the water but gets a slightly bigger in the pool. I assumed it would have been even more perfect if I bought it a size down. But I love it so much though! And it is sooo comfy and soft.

So, make a long story short, I am going to buy a second one! Been eyeing this suit for a while and glad I bought it. It’s an investment piece that’s high quality. The navy blue color is beautiful, and the suit fits perfectly and stays in place while you are swimming. Super comfortable, supportive, and stylish. Overall, I highly recommend it. 10 out of 10! For reference, I’m 5’5/34C/160 lbs, and ordered a 32 Regular. I'm thinking of ordering 32 Tall for the next one because 32 R is just a littl...

I absolutely adore this swimsuit!!! It’s perfect for doing laps in the pool and wanting to look cute at the same time! I will definitely be ordering from here again :) If you’ve been eyeing this swimsuit - this is your sign to get it!

Best swimsuit I’ve ever had! The material is so firm and feels amazing, I feel comfy but secured at the same time. Fits perfect to size, I’m a size 10 and 5’7. Only problem is now I want to buy one in each colour! 🫣

This is a perfect swim suit for me . I was lucky to find exactly what I wanted. Thank you for enabling my dream attire for the beautiful lap swim . Adorable color block design , great fabric content, because i am allergic to the polyester stuff . That was not easy to find all qualities suitable for me . Yes - to quality ! Galina.

Natasha M.Verified

Love the quality of the fabric, feels nice and sturdy, so I'm hoping with good care it will last longer than your average swimsuit. Also love the colour, and that you do a full tall range of swimsiuts that aren't frumpy/mumsy. I'm long in the torso, doesn't mean I want to dress like I'm 50.

I could not be more in love with this swimsuit!!! I swim a lot so I've tried all the usual big brands over the years but this is my new favourite for comfort, quality and fit. It's so flattering for a one piece - I get so many compliments in this. The sizing is spot on - definitely worth measuring and using their size chart. Can't wait for my next one in a new colour 💗.

Love Instant Swim Karma Onepiece!!! I love the cut and the straps. It fits perfectly and I am able to train in it without issues. The fabric feels super soft and durable. I would definitely recommend Instant Swim.

I love this suit! It allows me to be active, while wearing a more fashionable suit. I have swam many laps in this suit and it doesn’t rub my skin in the wrong places or slip out of place. I highly recommend!

LOVE these swimmers!! I bought them for the beach and have so far been extremely happy with the support and style they provide. They dry super quickly too! Couldn’t recommend more ✨

Customer photo review of Seamless Swim Cap

Aryn J.Verified

My new go to silicone swim cap! Very stretchy and easy to put on. Will note that it is a tab shorter than my Speedo and Nike caps (see photo). So if you are looking for a cap to help with getting your tanline closer to your hairline, this is for you! Will be purchasing more.

Joungmin L.Verified

size tip; too short torso, I think this suit is made of a little bit small. (28 means 27) It's made for training, but it's a beautiful back design so that'll be worn in a resort. Oh, the cut is low. 😉

June G.Verified

It looks and feels great! Thankful to the size guide that makes it easy to pick your true size. Love the design and looking forward to show it off in the pool:)

My daughter Vita swims 22 miles every month for different charities. She set this goal in January 2025 and is on track to complete 528 miles by the end of the year. Her well-being, confidence strength, fitness, and vitality has gone from 0 to 100% and I'm so proud and happy for her She loves her new instant swim, she looks great and feels fab. Instant swim cossies have a good fit, allowing for shoulder rotation and support in all the right places. They are wearing well , in sea and fresh wate...

Sharing this to help someone else with sizing. I originally ordered 32 regular after asking for advice with fit and was recommended the regular however I couldn’t stand up straight so sent back £9 restocking fee (which I totally understand as it’s a small business) and swapped for 32/tall (pictured) and I love it! Slightly more of wedgy than I’m used to but apparently that’s ‘in’ these days! For reference and comparison to photo: I’m 5ft 7’’ normally wear a Speedo size GB14/36 my measurements ...

Charly P.

I spent ages deliberating buying this (over a year!) because I have bought so many gimmicky products that I’ve been advertised that haven’t been even close to worth the price. So pleased to say that this isn’t one of those. It has just arrived and the quality is absolutely outstanding, and such a nice swimsuit! I have yet to wear it in the water but I can only assume it will hold up very well. As usual with swimsuits, this does come up very small. I purchased a Medium Tall as I have a long torso...

Georgie T.

Bought this as I don’t do bikinis and didn’t want to wear a classic racing suit on my holidays! On my last holiday I entered a very spontaneous long distance open water swim race and only had the option to wear this (my ‘leisure costume’) without wetsuit etc. I was a bit anxious it might not be up to the demands but as described it was perfect and super comfy, great for racing & I felt very happy wearing it! It is very flattering and I have many comments on it and will definitely be back for ...
