Meghan was seen walking into the service in a $1,199 Amanda Wakeley coat and dress and a beret by Stephen Jones. Duchess Kate looked equally as stunning in a much darker look -- a dark blue Beulah London coat dress with a matching Lock and Co hat she previously wore for the Grenfell Tower Fire memorial in late 2017.

This isn't the first time Meghan and Kate decided to coordinate looks. For their first public engagement together in late February, the future sisters-in-law donned similar blue looks -- Meghan in a belted Jason Wu dress and Kate in a recycled Seraphine frock.

And while we're lovin' the coordinating action between the two, we also can't help but notice how much blue Kate has been wearing throughout her pregnancy, especially in recent weeks. Is she trying to hint at the gender of baby No. 3?
