... Meghan is 180' in the other direction: low key, but classy and elegant. With her it's in the details. It's also possible that since she comes from a flashy background, she is more comfortable not being flashy now when her very position makes her front and center wherever she goes. Why gild the lily?
I got that almost immediately from Meghan's first outings with Prince Harry to parts of Great Britain before the wedding. She was not yet married and she kept everything low key, conservative yet elegant with touches of her own personal style and edge, e.g., the unexpected McQueen tux at the Endeavour Awards, and the black Stella McCartney coat with black Huit denim jeans and the boatneck black and white plaid blazer in Wales. Plus, she kept to dark colors a lot, and she stayed understated. During the Wales trip, it struck me that Meghan was not trying to stand out, since she was already the center of attention. And also, she did not seem to want the focus to be so much on what she was wearing, but rather more on the community organizations and charitable events she and Prince Harry were promoting and supporting.
Even with her choice of wedding gown, she stayed simple and understated, yet as true to herself as she could be within the traditional confines of a royal wedding. After the wedding has been a different story. Even before the wedding, it was a busy and stressful time, even though joyful too I'm sure. So there were a lot of decisions to be made, and she was surely planning some of her daytime outfits post-wedding at that time. I think she is experimenting right now and trying to meld her personal style with her new role, and it's not fully worked out right now.
However, just like Michelle Obama, I think it's true that while Meghan enjoys fashion, she is not interested in everything being about her clothes with the media. And she's definitely not a person who is interested in being flashy. Her job as an actor demanded some flash and dash because there was a need to stand out. Now, she has no need to stand out because all eyes are already on her. As part of the royal firm, the 'what to wear' decisions do become a bit more complicated. Meghan seems to be trying to keep it as simple and low key as possible, while experimenting and maintaining her own unique signature touches. She actually never was very flashy anyway as an actor. It's just that she took more risks and wore more cutting edge designer outfits and minis to premieres, which she won't be doing anymore.
Meghan once spoke about how her style changed once she began filming
Suits, after meeting top designers, and also meeting stylist Jessica Mulroney on the set. Meghan said her laid-back California casual style became more sophisticated and upscale, but still with her own unique edge. She's now in the process of undergoing another style evolution. I don't think her love for basic colors, monochrome dressing and stilettos will change too much. We've seen her wear lots of black, navy, white, cream, burgundy and occasionally brighter colors, like yellow, green, and pink. And she's worn flower prints, but not very often. I wonder if/when we'll ever see more biker jackets. My favorite Meghan outfits during her dating days are the Antonio Berardi navy dress worn to watch Harry play polo in May 2017, and the burgundy pleated dress with darker burgundy biker jacket (monochrome style) that she wore to the Invictus games opening night in Toronto (September 2017).
