At the christening of the HMS Glasgow in Scotland on Thursday, May 22, the Princess of Wales turned heads in a nautical-inspired coat dress. The elegant navy-and-white design closely mirrored a similar look Diana wore during a Battle of the Atlantic service in 1993. The late royal’s outfit, also in navy and white, was designed by Catherine Walker.

To christen the Royal Navy ship HMS Glasgow, Kate Middleton wore a maritime-inspired ensemble that called back to an outfit worn by her mother-in-law, Princess Diana, in 1993.

The late Princess of Wales wore a strikingly similar outfit at a Battle of the Atlantic service in Liverpool in 1993.
