I actually get compliments on these bathers when I go swimming, they are so nice. The sizing guide is pretty accurate, just err on the side of caution when it comes to length, just because they do ride up quite high. You can see where your nipples are if it’s cold, so might be worth considering if you’ve got bigger ones! But the material does feel great, and the straps are nice and thick, so don’t stretch out easily like some other pairs. I want them in every single colour.

Great stylish swim cap - very comfortable and doesn't pinch or irritate my head!

Went for long body size 10. Im 6ft tall and finally have a swim suit that sits on my body in the right places

I have always struggled with getting a swimsuit that fits my body whilst giving me support for my boobs. I am currently a 36 E and size 12 so wear a large in the swimsuit. I wore this in the sea in the UK followed by the water parks in Orlando. I didn’t have one single issue with it. No nip slips, full support and pure comfort with style all in one. I was even able to wear it with a skort and it looked like a put together outfit so I could go out after water activities. So many compliments, I am in love with this swimsuit.

Amazing swimming costume. I love it. Tall length in this style please, and would love a style with a less high cut leg / more bum coverage. Thanks so much for making such lovely and functional swimwear 😊

Customer photo review of Karma X Onepiece - Jade

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.

Love the colour and the fact that it’s reversible! Runs a bit tight/small

Customer photo review of Seren Onepiece - Neon Cherry

I have been looking for a functional, chlorine resistant, but sexy swimming costume forever. I don’t think I will buy one anywhere else now! I love this. If it lasts as long as your reviews suggest I’m a customer for life. My only request would be for a swimsuit version that is not so high cut over the leg / bum to preserve modesty over bikini line! (And tall versions in all types would be lovely!) Thank you- I love it.

Customer photo review of Raya Onepiece - Matcha/Latte

Such a fantastic swimsuit. I feel amazing in it, it doesn’t ride up or drag down, is very comfortable, and I feel like it’s great both for a swim session or for playing in the pool with my daughter. Two great colours in one as well! I’m 5ft8, size 10 and was grateful for the tall option.

I’m a uk 8-10 & 5 ft 6 and went for a small. I debated between small & medium but happy I went small- it’s snug but really comfortable.

Customer photo review of Snake Chain Bracelet

I really enjoyed having an accessory when going for a swim. Since the chlorine had damaged some of my other necklaces and earings so this was a lovely addition and alternative. Unfortunately for me, I have very (very) small wrists and most items, from watches to bracelets, are too big for me. This is still running on a looser side, however it had reliably stayed on and I had not worries about it falling. I really enjoy this lovely edition and look forward to seeing what other things will come out from this lovely brand!

Customer photo review of Raya Onepiece - Neapolitan

Absolutely beautiful swimsuit, as a 5’11 girly I was so pleased to see 5’8+ girls are catered for, unfortunately the fit just isn’t quite right 🥲 it gapes really badly at the front as soon as my arms are in a streamlined position, and as a freestyle swimmer that’s not ideal 😅 I don’t think I could’ve sized down as it would be too tight across the shoulders (a problem most swimmers will have 🤣) as it already feels like it rolls up a little bit, such a shame, so I won’t use it for training but I will definitely take it on holiday for boat trips & sea swimming when I’m not as competitive, as other than the above it’s really comfy and a flattering fit 😊

Great swimsuit, slight discolouration on the lighter colour but feels like good quality.

Customer photo review of Raya Onepiece - Sangria

Gorgeous quality swimsuit in fab colours! I got tonnes of compliments when wearing this. I had a slight issue with sizing and feel like I may have been better off with a tall version as it felt a little tight on the body length, and it felt like water was going straight down the top where it was over stretched, so hopefully the next one will fit better.

Customer photo review of Lyra Bottoms - Onyx

I absolutely love the bikini bottoms! They have a silicone grip on the inside that keeps them securely in place, so they don’t shift or ride up while swimming. They feel really comfortable, stay put, and give me confidence in the water. Such a thoughtful feature that makes a big difference!

Customer photo review of Lyra Top - Onyx

Great bikini for swimming! It stays in place while I swim. The fit feels secure, though I’d recommend adjusting the top straps to a tight fit before wearing it, as they can be loosen while swimming. The fabric is supportive and comfortable. Definitely recommend it if you’re looking for a practical yet stylish bikini set.

Customer photo review of Karma Onepiece - Siren

This swimsuit is incredible! Finally a flattering swimsuit available in tall where there's no risk of a boob popping out! The straps are SO comfortable that you don't notice them at all - I regularly swim 2k breaststroke and have zero red marks afterwards. I do find it sometimes rides up a little bit, but it's still comfortable even when it does. I love it and want more!
