First, make a simple syrup: In a saucepan over medium heat, combine sugar and 1 cup water and stir until the sugar has dissolved. Remove from heat and let cool.
In a large pitcher, stir together simple syrup and lemon juice. Top with cold water and stir together.
Refrigerate until ready to serve. Pour over ice and garnish with lemon slices, mint leaves or fresh fruit.
