At her royal wedding, Princess Eugenie wore a dress with a low-cut back that revealed a long scar from an operation on her spine, inspiring others with back scars to share photos and feel more comfortable with their bodies.

Eugenie, who had surgery to correct her scoliosis at age 12 according to CNN, worked with designers Peter Pilotto and Christopher De Vos on her wedding dress. The low-cut back is deliberate, and meant to show her scar.

She spoke about the design decision in an interview on ITV, saying, "I think you can change the way beauty is, and you can show people your scars and I think it's really special to stand up for that."

Eugenie's decision to refrain from hiding her scar caught the attention of others with scars from scoliosis surgery, who voiced support for Eugenie and spoke about how it was inspiring sight to see.

Scoliosis is a relatively common condition in which a person's spine has an abnormal curve to it. While some cases are relatively mild, more extreme instances of scoliosis can be treated with surgery to improve posture, reduce pain, and lessen the threat of more serious complications.
