Our Founder


Hi, I’m Niamh - the founder of That ‘Kini.


My journey into swimwear started back in 2018 when I began studying fashion design and marketing, later specialising in swimwear during my final year. It was during this time I realised how many gaps there were in the swimwear market -pieces that didn’t fit properly, didn’t feel right on, or simply weren’t designed with real women in mind.

That’s where That ‘Kini began.

Since launching, the brand has grown and evolved into its second year of trading. What started as a made-to-order model has now developed into a blend of both handcrafted pieces and styles produced with a trusted manufacturer, allowing us to scale while still maintaining the attention to detail and fit we’re known for.


Every design is shaped by real feedback from our customers, with a focus on creating swimwear that feels confident, flattering and effortless to wear.

At That ‘Kini, it’s about more than just bikinis - it’s about pieces that make you feel like the best version of yourself, whether you’re poolside, on holiday or heading to a beach club.

I genuinely can’t explain how it feels seeing you all wear my designs. Thank you for being part of this journey and supporting my small business - it means everything.
