SANTAI-SANTAI
We believe getting dressed should feel like an extension of who you are.
Our mission is to create joyful, expressive clothing that gives you the confidence to take up space, embrace colour and show the world who you are without saying a word.
Because in a world that so often asks you to conform, we hope our pieces remind you that the best thing you can be is yourself.
Note From Founder
Santai-Santai is our way of bringing you into our island life.
Santai-Santai is Indonesian for relax or chill out. It's a mindset that's woven into everyday life in Indonesia. Even when there are challenges, there's a reminder to stay balanced, stay light-hearted and enjoy the present moment.
This collection is about chasing a life you don't need a holiday from.
The silhouettes are playful while still staying true to our signature style and versatility. We took inspo from the iconic Chanel '90s runway shows and 60s retro swimwear. Fashion through the eras has always been one of my biggest passions, and being able to bring those influences into functional pieces you can actually live in is the coolest blend of everything I love.
I can't wait to see you wearing these pieces.

Let customers speak for us
from 20 reviewsThis dress has genuinely become part of my personality at this point 😭 I’ve worn it on the tube, to exhibitions, dancing, it moves with you and photographs itself honestly. The colours are stunning in every light and the print details (turtles! suns!) make it feel so special, not just another slip dress. Getting stopped for compliments every single time. Subtle Poison never miss, this brand just gets it. 10/10, already thinking about what I’m pairing it with next xxx

I got the Subtle Poison seashell swimsuit as a Christmas gift to myself & I haven’t worn any of my other swimsuits into the sea since because nothing compares. It’s my all time favourite! Also got to wear it to two fun events my family Christmas swim & my first loony dook in Scotland and got loads of compliments!

I love my nautical swimsuit so much! I have been wearing it while surfing the past few weeks in Sri Lanka. It is so comfortable and makes me feel so good surfing! Last week a lovely gal recognized me from the swimsuit design. We stopped and had a lovely little bonding moment! I will always support this lovely brand and the lovely community that comes with it ❤️

Grainne is a saint and there hasn't been a single order I've made that I wasn't happy with!! ❤️ The fleeces practically sponsored my ski holiday and the other fits were glowing at skate love!!!

Absolutely adore my fleece and swimsuit! I messaged Gráinne to ask if she had a particular product in stock and she went above and beyond to help me out. The colours are stunning, everyone always compliments the pieces on me:)
Dopamine in a dress, I feel so connected to my inner child wearing it but so sexy as well! Almost TOO gorgeous to wear to the beach but one things for sure I will be getting my wear out if it once the sun shines I’m not sure I’ll ever take it off. 10/10. Stunning xxx
Wow, this has been the swimsuit I have been searching for. Trying on swimsuits can be so umcomfortable and theres always one part that stops me from feeling fabulous. But this is NOT the case for Subtle Poision. The Aqua Nautical swimsuit checks every box!! Its given me so much confidence. The fabric is STUNNING, the design entirely unique and carrys curves, bums & boobs well without flattening or making you feel self consious. Every time I wear I feel my sparkle back. Worth every penny and I know Ill have it for years and years to come🩵🧜♀️✨️💖💖
Thank you Gráinne for creating this beautiful collection and brand for all✨️
*I also very kimdlg received bikini bottoms and they follow the same standards of high Quality and wearability. I wear xs in them and S in swimsuit. I probs would try medium next time in swimsuit but I also love the way The S is figure hugging. ( I Fluctuate - depending on time of month between and 8 - 10/12 UK size )

I bought both versions of this as it's sooo cute and cosy and practical. I wear it skating and swimming and I feel protected but very cute at the same time. The fit is spot on and the colours are even more impressive in person.
I am so in love with this dress I wear it every chance I get. Fits perfectly and flows so flattering. It goes so well with the other pieces too and I love pairing it with the reversible swimsuit. The colours are sooo beautiful and the quality is 10/10.
I'm so obsessed with this swim suit, I get so many compliments every time I wear it. It's reversible and both sides are equally beautiful. So comfy to wear and very flattering. I've bought a few pieces now and the quality is always 100%
I wore the SONAS - Long Sleeve at skatelove and I’m so glad I took so many photos in that top because looking back on that whole trip l, my favourite fit was when I was wearing subtle poison 💕
The fabric is so nice and stretchy, perfect if you’re in between sizes.🙌
This is perfect for keeping a little bit warmer during colder dips because it has a sleeve but also is so cute to just wear as a regular top or even as a workout top! I love the cut out in the back and the half zip feature on the front. The colours of this product are amazing, couldn't believe my eyes when I got it!!
When this product arrived I couldnt believe how vibrant the colours were in real life. The design is gorgeous and the shape of the bikini is really flattering. It stays on even when the sea gets a bit crazy which we also love!!
Obsessed with how this is reversible and the blue on the inside is my favourite colour blue ever! Love how the colours pop, especially in the sun and the fun ocean-themed pattern! Very high quality and definitely super flattering on too
The fabric is so soft and comfortable. Perfect for yoga, skating or any sporty activity. Plus they are so soft pretty! Highly recommend girlies!!
The romper you won't wanna take off this summer!
Our Santai Santai romper gives you two looks in one. One side features our signature retro-inspired wavy polka dot print, while the reverse reveals classic horizontal stripes.
Designed with a scooped open back and a soft, sculpting fit, it's the easiest thing to throw on after a swim, style with an oversized shirt or dress up for sunset drinks.
