2018 - Green means reuse
Kate's 2018 appearance at the Irish Guards' St Patrick's Day Parade looked very similar to her 2017 one. The royal opted to wear a similar Catherine Walker coat to the event at Household Cavalry Barracks in London. Of course, she had a booming, notable difference - she was pregnant!

2015 - Breaking tradition
Pregnant with Princess Charlotte, Kate opted to forgo her traditional green style, instead donning a brown swing coat and high heels for the parade at Mons Barracks. However, the coat was not too far from her usual choices in that it was designed by Catherine Walker. She paired the look with a favorite Lock & Company hat, Kiki McDonough earrings, and shoes and clutch by Emmy.
