The typical garnish for an Amaretto Sour is a maraschino cherry. This garnish is commonly used, as it not only adds a pop of color but also complements the sweet, almond flavors of the amaretto. The maraschino cherry can enhance the drink's presentation and provide an additional layer of sweetness that pairs well with the tartness of the lemon juice used in the cocktail.

While options like a lemon slice and an orange slice could theoretically be used in some variations for aesthetic purposes or personal preferences, they are not standard garnishes for an Amaretto Sour. Similarly, the option suggesting no garnish does not align with the common practice of garnishing cocktails, especially popular ones like the Amaretto Sour. Thus, the most appropriate and traditional garnish for this drink remains the maraschino cherry.
