News Pregnant Kate Middleton's Maternity Outfits Will Remind You of Her Engagement By Alexandra Whittaker Updated on February 7, 2018 @ 11:30AM Pin Share Tweet Email Kate Middleton is feeling the fashion blues with only a few short months to go before her due date. The royal has been stepping out in a lot of the same color lately, from the unconventional velvet-patterned gown she wore in Sweden to her most recent tour de force that she wore while back home. After Middleton returned to England after an official royal trip to Sweden and Norway, she wore a bright blue coat by Goat while opening the Action on Addiction treatment center in Essex on Wednesday: Stuart C.

Middleton wore a similar color while on her Scandinavian tour as well.

This particular shade of royal blue is similar to the color she wore during the announcement of her engagement to Prince William—and it also mirrors the 18-carat sapphire engagement ring she wears on her wedding finger to this day.

Only time will tell if Prince George and Princess Charlotte end up with a little brother after all.
