The butterfly is a very old symbol for joy and good fortune. In some parts of the world big swarms of butterflies are actually released in connection with weddings and other big occasions, and bred for that sole purpose. So having butterflies right there on your pocket square will hardly do any damage when you're doing the deed. Vingslag Beige is a playful yet sophisticated hanky, and thanks to the low-key palette you're open to colouring up a bit on other details. Congrats and good luck!
