SIRIVANNAVARI Unveils Princess Collection 2026, Raising Breast Cancer Awareness Through “Heart for Hope”
The fourth edition of the SIRIVANNAVARI x WACOAL collaboration combines thoughtfully designed lingerie and leisurewear with meaningful social initiatives, including free breast cancer screening services for the public.
In recognition of Breast Cancer Awareness Month, SIRIVANNAVARI presents Princess Collection 2026, a special annual collaboration with WACOAL Thailand under by the vision of Her Royal Highness Princess Sirivannavari Nariratana Rajakanya, the brand’s Founder and Creative Director. Now in its fourth consecutive year, the initiative brings together fashion, and community engagement to raise awareness of breast cancer, encourage early detection, and promote women’s health and well-being in Thailand.
This year, the collection has been unveiled alongside a series of social outreach activities. The initiative is supported by three partner organizations: the Queen Sirikit Centre for Breast Cancer (QSCBC), King Chulalongkorn Memorial Hospital, Thai Red Cross Society, the Kanchanabaramee Foundation, and the National Cancer Institute, aiming to encourage preventive healthcare, expand awareness of breast cancer screening, and provide support and encouragement to women and cancer patients.
First launched in 2023, the Princess Collection reflects Her Royal Highness’s concern for Thai women’s health and quality of life. The initiative encourages women to recognize changes in their bodies, seek professional medical advice, and undergo appropriate screening to support early detection. Beyond physical health, it also emphasizes emotional well-being and the importance of extending compassion, care, and encouragement to patients and their loved ones.
A key highlight of this year’s event is the provision of free breast cancer screening services for the public. The Kanchanabaramee Foundation deployed four mobile medical units, including mammography-equipped vehicles for breast cancer screening and mobile clinics offering gynecological cancer screening services. Medical team provided screening services at the parking area of House No. 1 from 26–27 October 2026, helping improve access to preventive healthcare and promote early disease detection.
The event for social impact also featured educational activities on breast cancer prevention and screening, alongside exercise sessions and holistic wellness initiatives organized in collaboration with the three partner organizations.
Extending the spirit of care beyond medical services, WACOAL Thailand presented “Hat from Heart,” an activity inviting participants to sew hats for cancer patients. “Hope Space” offered visitors an opportunity to share messages of hope and encouragement, while an exhibition showcased the inspiration and creative process behind Princess Collection 2026.
The program concluded with “Aerobic Dance,” an energetic group exercise session inviting participants to dress in pink and celebrate the importance of an active lifestyle. Led by Rusameekae Fagerlund with aerobic trainer and influencer known as @krutuksuanlum on TikTok, the activity brought participants together in an uplifting atmosphere, reinforcing the message that caring for one’s health can be both empowering and enjoyable.
Princess Collection 2026
At the heart of Princess Collection 2026 is the concept “Heart for Hope,” which expresses love, compassion, and optimism through SIRIVANNAVARI’s distinctive design philosophy, complemented by WACOAL Thailand’s expertise in lingerie craftsmanship. The collection embraces a wellness-oriented approach, balancing refined aesthetics with comfort and functionality.
Lightweight lace and skin-friendly fibers create a soft, second-skin feel, while floral cutwork, delicate ruffles, and intricately twisted fabric details inspired by draping techniques lend the designs a graceful, feminine character. Every detail reflects a considered approach to contemporary femininity, with comfort and well-being remaining central to the collection.
The color palette combines understated elegance with fresh, vibrant accents, featuring cream, ivory, butter yellow, grape green, peach melba, burnt orange-brown, and black. A signature heart print designed exclusively for the 2026 collection serves as a defining motif, symbolizing love and hope.
Beyond lingerie, the collection includes leisurewear and resortwear, featuring sleepwear and robes designed for versatile styling. These pieces bring together fashion and functionality, extending the collection’s distinctive aesthetic into everyday life.
Princess Collection 2026 is scheduled to launch in November 2026 and will be available at the SIRIVANNAVARI flagship store on the first floor of Siam Paragon, through the LINE Official Account Sirivannavari BKK, and at participating WACOAL shops and counters in leading department stores.
A portion of the proceeds from sales will be donated to the three partner organizations to support their work assisting breast cancer patients and raising awareness of women’s health in Thailand.
Through Princess Collection 2026, SIRIVANNAVARI and WACOAL demonstrate how fashion can serve as a meaningful platform for social good. By bringing together creative expression, community participation, and a shared commitment to women’s health, the initiative continues to spread a message of love, hope, and solidarity—encouraging women to prioritize their well-being and fostering a more informed and compassionate society.
