They may be extremely different women, but Kate Middleton and Meghan Markle’s styles have many things in common.

We could search the whole world and still not find two people more different than Kate Middleton and Meghan Markle. From their upbringing to their education — and the way they speak to the activities they’re into while off duty — there are some stark difference between these two royals.

Their style is different as well. The Duchess of Cambridge’s style could be described as elegant and conservative, as befits her role as future queen consort. The Duchess of Sussex, on the other hand, is much more fashion-forward and laid-back at the same time. But that doesn’t mean that their tastes don’t sometimes overlap. There have been plenty of times when the two duchesses have practically been fashion twins — or at least have used very similar fashion elements, and put their stamp on them.

Both Kate and Meghan clearly put a lot of thought into what they wear. Their clothes have to be appropriate for whatever event they’re attending, and they have to pay attention to the clothes’ fit, sheerness, length, cleavage, etc. Both of them also send messages with their outfits, whether it’s a subtle nod to Princess Diana or an overt tribute to a host country.

But of course, through all this, they have a lot of personal choice. They ultimately pick clothes they feel comfortable with, and plenty of times, the outfit each has picked out for herself looks like something the other would wear — even with some stylistic tweaks.

There have been similar dresses, shirts, jeans, and blazers, and similar colors, necklines, and fabric patterns — enough to make us wonder if they’ve ever called each other before an event to get dibs on wearing a certain dress color (or a certain style).

Whatever the case may be, every time they make a public appearance, it’s fun to check out Meghan and Kate’s outfits and think back to when the other person might have worn something similar. Here are 19 Kate and Meghan outfits that are quite similar.
