Heart of Sun was born from the love of dancing under the sun, unafraid of what’s next. It's for all the babes whose hearts shines like a million suns. Expressing freedom, confidence, love, & unwavering unity.   


Growing up in Miami, Florida, with the ocean as her backyard & all her summers spent in the Bahamas. Designer Sophia Lima knows that a girl's swimwear collection says a lot about her. So she set out on a journey to create swimwear that not only makes girls feel like the bombshells that they are but pieces that are bold, unique, and tailor-fitted for all body types. 

With a deep appreciation for all things vintage, each bikini is designed to make you reminisce on all eras of the past. Our passionate focus on quality, detailing, and the perfect fit will make you look and feel like the ultimate #HOSBABE.

Sophia’s designs have been worn by supermodels and celebrities, including Bella Hadid, Kourtney Kardashian, and Sofia Richie. As well as featured in dream publications including Vogue, Harpers Bazaar, Sports Illustrated, & many more.  



Our swimwear + beachwear is designed with your curves in mind. Using the highest quality, Italian imported fabrics, custom metal details, & exclusive print designs and colors. Each piece is handmade to order in Miami, Florida, by our female ran team.  



We value ethical and sustainable practices. Our earth & friends always come first. We do not mass produce and will always prioritize ethical practices. Our goal is to minimize waste, so we make limited productions using lycra made of recycled plastic water bottles. Our items are made start to finish in our in-house factory; this allows us to reduce our carbon footprint.

Our 100% female production team is dedicated to perfecting our fit, designs, and brand from start to finish. Our team is ethically employed, working in healthy and safe conditions while receiving an above-average living wage. Most importantly, we are always kind to each other. Our team is compassionate, supportive, and caring - a lovely place to work. We know that ethical fashion is a term used loosely in the fashion industry today. As a brand using this term, we wanted to explain in detail how we are following through with our promise.We consciously design & hand make our items in the same building located in Miami, Florida. This keeps the carbon footprint of each garment to an absolute minimum. Our goal is to create garments that make our customers feel confident in their own skin. In addition, certain products are made to order, and we only produce what is needed to meet the demand.

ECONYL@ our swimwear fabric is fashion with the most negligible environmental impact possible; this sustainable fabric is made from recycled plastics and fishnets. Saving about 92% of energy, reducing CO2 emissions by 72% only in the production of the fiber, & benefiting more than 50,000 families of waste recyclers. Our goal by the beginning of 2022 is to design a collection made up of all sustainable fabrics.All of our swimwear bags are produced of 100% recycled materials. This packaging can be reused as a cosmetic, beach, or wet bikini bag. Our poly-mailers and tissue paper are also produced of decomposable recycled materials. Our packaging is a step toward ending the use of environmentally harmful materials. As our company grows, we will work to make all packaging accessories recycled.
