Put the dark chocolate and white chocolate in separate metal bowls.
Fill a small sauce pot with an inch or two over medium high heat. Bring the water to a very light simmer and put the chocolate bowls over the water one at a time, until the chocolate is melted. Continue to stir the chocolate both as it melts, and once you've removed it from the water, to help distribute the heat evenly.
Once the chocolate is melted, dip each of the strawberries into either the chocolate or white chocolate. For a smoother finish, dip the strawberry once and hold it above the chocolate so that it can dry just a bit, and then dip it again to create a nice and smooth layer. Place the strawberries on wax paper or parchment paper to dry.
To make tuxedo strawberries, dip half the strawberries in white chocolate. Place them on parchment for at least 5 minutes so that they can dry.
Take the strawberries and gently dip one side, and then the other, in dark chocolate. You want a "V" shape in the center, and the strawberries will almost have a heart shape. Again, place on clean parchment paper to dry.
Use a paper cone to decorate the strawberries with bow ties, or as desired, before serving. Serve slightly chilled or at room temperature for best results.
