In the world of Meghan Markle and royal fashion, there's BRW and post-BRW. That'd be her wardrobe before the royal wedding and the subsequent neutral outfits that she's been trotting out post-wedding. According to Cosmopolitan, there could be a very good reason for it: she doesn't want to clash with the Queen. But could it go beyond that? We've got some ideas.

She's becoming more comfortable as a royal

A steady rotation of navy, gray, and black (and some green) means that Markle will never risk outdoing the Queen herself, who's known for her eye-catching ensembles, most of which feature bold colors.

Lucas Armitage, a style commentator, told The Daily Mail that Markle's probably keeping the Queen's style in mind when she's choosing outfits for herself.

"I feel this is a clever styling tactic as it will always work with the Queen's look; she is known and applauded for her use of bright fun colors. The use of neutral color on Meghan's part is also a show of respect to the Queen so she never looks like she is trying to outshine her," he said. "I think the Queen and Meghan's relationship at this point is one built on respect, and Meghan has shifted her own personal style to adopt a more demure regal look -- something I think the Queen will be thankful for."

But it could be Markle's just getting more comfortable in her role as a royal. She once told AOL that her personal style was "bobret," a mix of boho and Breton. That explains the striped Ralph Lauren look, the trench dress, and even her preference for simple sheaths. She could just be going back to a more understated version of that.

It's fall, y'all

Markle could just be moving towards everyone's favorite season. Now that it's fall, it makes sense that she's not wearing bold color and opting for autumnal staples. It's not unusual for a closet to go from full-throttle to neutral when the temps start to drop. Think: navy blue peacoats, tan trench coats, and black knitwear rules just about everyone's wardrobe come fall. There's no reason a royal would be immune to the same seasonal shift.

The change pulls double duty, too. If Markle is hoping to steer clear of upstaging the Queen's colorful outfits, staying classic will make sure she's a complement to any royal, not a competitor, when the flashbulbs go off. With the changing season coming for everyone, royal or not, having Markle's coat collection as inspiration will certainly help out.
