Tarna Mint pocket square is an excellent spice colour for a light-coloured summer suit. It will work fantastically as accent to rusty red or orange, so if you put that on your tie you have several possible suit colours. Pastel colours as mint do stand out quite a bit, which is probably what you're after. So a suit with some pattern could help build a noteworthy, high-profile look. To maintain a higher contrast, choose a lighter suit, to play things down, select a darker one. Tarna is a great ingredient for any party garb.
