In 2014, the Linfield FC shop on the (predominantly Loyalist) Shankill Road in Belfast put a sign in the window to clarify that the orange, white and green flag on its World Cup bunting was for the Ivory Coast 🇨🇮, not Ireland 🇮🇪.

From the World Indoor Athletics Championships in Birmingham in 2018.

“Ivory Coast's Murielle Ahouré stormed to glory in the women's 60m and as she celebrated, she realised she had no flag to drape around her shoulders.

Up stepped quick-thinking Irish fans in the crowd who threw her a tri-colour which, of course, is the exact same as an Ivory Coast flag when flipped around the other way.“

Pedants may note that the Ivory Coast flag is not “the exact same” as an Irish tricolour upside down. A proper Irish flag has proportions of 1:2 whilst an Ivory Coast flag has proportions of 2:3. The Irish flag is longer and narrower and the one in the picture looks more like a 2:3 flag.
Whoever made the sashes for Mayor Mamdani and other New York officials for St Patrick’s Day did not notice which way round the flag goes.
@Nickiquote The last Irish flag I saw had proportions of √2:√3.
