Preface: I have searched around and read many posts about summer wedding suits, but could still use some advice on accessorizing. I am getting married this summer, and it is going to be a small, outdoor affair. I bought a BB Fitzgerald suit with the pattern shown below, and am wearing it with dark brown, perforated cap-toes. I am also wearing a white, spread collar, french cuff shirt. I would like to dress this up with a pocket square, but this is my first foray into pocket squares. I have not decided on the tie yet, but have been looking for a paisley print with elements of brown (to highlight the brown deco pattern in the suit) and light blue/teal to add some color. What kind of pocket square should I be looking for? I was thinking about a plain white with a colored border to highlight the colored element of the tie. Any thoughts or recommendations are welcome.
