As you can see its paired with the white shirt and black suit, and a white square. However we don't have to stay with that.
So I tried a bunch of different shirts that on principle might have worked but they didnt pass the eyeball test. First of all I swapped the black suit for a more versatile Charcoal. Then I was left to find acceptable shirts.
The pink fell short because it looked fruity even with the traces of pink in the tie. I wont even post the blue
I then tried this Hickey Freeman Hist First lilac striped which was perfect for both the suit (this suit has a lilac stripe in it. Also a Hickey Freeman) and the tie. I tried the pink trimmed pocket square because I wanted that pink in there. It wasnt the best option. Better still was the light blue pictured just below.
Swapping suits for a plain Charcoal Pin stripe but keeping the shirt and tie I added the blue trimmed square for a nice look. The blue in the square pulls the shirt which also has a blue stripe together and the traces of blue in the tie. I like the look.
Have a great weekend!
