PRINCESS COLLECTION 2026: SIRIVANNAVARI’s Annual Breast Cancer Awareness Initiative, Inspired by the Vision of Her Royal Highness Princess Sirivannavari Nariratana Rajakanya

SIRIVANNAVARI x WACOAL Launches the Royal-Designed “Princess Collection 2026” Lingerie and Leisurewear Collection, Alongside Public Breast Cancer Screening Services Provided by the Kanchanabaramee Foundation to Raise Awareness Among Thai Women

    In October, which is observed worldwide as (Breast Cancer Awareness Month), SIRIVANNAVARI continues the vision of Her Royal Highness Princess Sirivannavari Nariratana Rajakanya, the brand’s designer, to raise awareness of women’s health and the importance of breast cancer screening—a disease that is the most commonly diagnosed cancer among women worldwide. The fourth consecutive year of the Princess Collection 2026 project is being carried out in collaboration between SIRIVANNAVARI and WACOAL. The partners are also launching a royal-designed lingerie and Leisurewear collection under the concept “Heart for Hope.” A social outreach event was held on 26 October 2026 at House No. 1, Soi Charoen Krung 30, Bangkok. Three partner organizations—the Queen Sirikit Centre for Breast Cancer at King Chulalongkorn Memorial Hospital, Thai Red Cross Society; the Kanchanabaramee Foundation; and the National Cancer Institute—joined the initiative to promote health awareness and offer encouragement to Thai women.

    The Princess Collection project was established in 2023, inspired by Her Royal Highness’s concern for women’s health and quality of life. Recognizing the importance of breast cancer awareness, the project encourages women to regularly observe changes in their bodies and undergo screening as recommended by medical professionals to improve the chances of early detection. It also emphasizes physical and mental well-being, while extending love, care, and encouragement to patients and those around them. These principles remain at the heart of the project, which Her Royal Highness has continued to support.

A key highlight of this year’s social initiative was providing the public with access to free breast cancer screening. The Kanchanabaramee Foundation brought four mobile units to the parking area at House No. 1: mammography units for breast cancer screening and mobile units for gynecological cancer screening. Medical teams and healthcare professionals provided services from 26 to 27 October 2026, promoting preventive healthcare and the early detection of disease.

     The event also featured educational activities on breast cancer prevention and screening, exercise, and holistic health, in collaboration with all three partner organizations. It provided opportunities to encourage cancer patients through WACOAL’s “Hat from Heart” activity, which invited participants to sew hats for patients, and “Hope Space,” where visitors could write messages of hope. An exhibition also presented the story behind the royal-designed Princess Collection 2026. The event concluded with “Pink Aerobic Dance,” inviting attendees to wear pink and enjoy exercising together, led by Rachakorn Fakuealon and Kru Tuk Suan Lum. The activities created a positive atmosphere and highlighted the importance of caring for one’s health in a joyful way.

    The Princess Collection 2026 was designed under the concept “Heart for Hope,” expressing love, care, and hope through SIRIVANNAVARI’s design philosophy and attention to detail, combined with WACOAL’s expertise in lingerie. The collection places equal emphasis on beauty and comfort in keeping with the wellness concept. It features lightweight lace and skin-friendly fibres that provide a(Second Skin) feel. Floral cutwork, ruffles, and carefully twisted fabric details reminiscent of delicate draping add a feminine touch.

     The collection’s colour palette balances softness and vibrancy, ranging from cream white(Ivory Cream)  , (Butter Yellow), (Green Grape), and (Peach Melba), as well as burnt orange and black. It also features the signature 2026 heart print, a symbol of love and hope. The collection includes Leisurewear and Resortwear such as sleepwear and robes, designed to be mixed and matched for everyday wear, combining fashion with functionality.

      Princess Collection 2026 is scheduled to launch in November 2026 at the SIRIVANNAVARI flagship store on the first floor of Siam Paragon, online through the LINE Official Account: Sirivannavari BKK and at participating WACOAL shops and counters in leading department stores. A portion of sales proceeds will be donated to the three partner organizations to support their work assisting breast cancer patients and raising awareness of women’s health in Thai society.

    Princess Collection 2026 is more than a celebration of fashion. It harnesses the power of creativity to share love, hope, and encouragement, while inspiring Thai women to recognize the importance of looking after their health and achieving a better, more sustainable quality of life. #PrincessCollection2026 #Sirivannavari #WacoalThailand #SirivannavarixWacoal
