Meghan Markle Effect? White Royal Engagement Coat Crashes Designer Website

Kate Middleton has been known to throw royal watchers into a fashion tizzy. Now her future sister-in-law, Meghan Markle, is having the same effect.

On Monday, Prince Harry of Wales, 32, and American actress Meghan Markle, 36, made their first public appearance as an engaged couple. When they stepped outside Kensington Palace and posed for photographers at Sunken Gardens, Markle's dress wasn't visible, but she wore an off-white (or "winter white") coat from a Canadian brand, The Label. Within minutes of the photos appearing online, the fashion line's website crashed from too many eager women trying to purchase a copy of Markle's coat.

Markle's $465 nude heels are from a designer line called Aquazurra.

Middleton, who is married to Prince Harry's older brother, William, tends to inspire women to buy out the designers she wears. The "Kate Middleton effect" went to work over the holiday weekend, when Middleton wore a crystal blue maternity gown to the Royal Variety Performance on Friday. Middleton's younger sister, Pippa, also sets trends with her apparel choices. British tabloids were flustered by Pippa's diamond earrings, which she wore while shopping in London last week.

Markle hasn't made her engagement photo-shoot dress public yet, but we might be able to form an idea of what she wore based on her now-shuttered fashion and lifestyle blog, The Tig. When it was online, she primarily suggested clothing with clean lines and polished details. Markle designed a line of spring dresses for Reitman's in a deal that closed in April. As Vanity Fair reported, Markle is passionate about sustainability and being environmentally conscious in both decorating and her personal style.

She probably got help choosing her dress from Canadian stylist Jessica Mulroney, her best friend. As the Telegraph reported, Mulroney is very familiar with the unique platform occupied by high-profile women, especially in global politics: She also has advised Sophie Grégoire Trudeau, wife to Canadian Prime Minister Justin Trudeau. "We had a responsibility to create more moments like that to give homegrown designers an international platform," Mulroney said in describing her work with Grégoire Trudeau.

It's unclear if Markle will begin wearing more British designers or if she'll stick to her favorites from the United States. Having a Canadian personal stylist means we'll probably see more of that country's designers in the royal mix, one that could spark huge profits for designers worldwide.

Markle and Prince Harry's official engagement photos have not yet been released, but the couple will wed in the spring.
