The Prince and Princess of Wales will visit the Irish Guards for St Patrick's Day.

Kate is expected to wear green, which is her tradition for the patriotic event.

Last year, Kate wore a military-style green coat with navy leather buttons.

Kate usually wears green coat dresses on St Patrick's Day, but in 2015, she wore a dark gray coat instead.

In 2016, Kate did not attend the St Patrick's Day parade.

The annual engagement was canceled in 2020 and 2021 due to the pandemic.

Kate often pairs her green coats with matching green heels and a green hat.

Kate wears military-inspired Alexander McQueen or Catherine Walker dresses for the event.

Recently, Kate wore an unusual navy peplum skirt suit by Erdem for the Commonwealth Day service.
