Choose a short or long-sleeved t-shirt to turn into a tank top. Go with a solid color for a clean-cut look, a football or baseball shirt for a sporty style, or a graphic Tee for a uniquely hip tank.

Put your T-shirt on. Look in the mirror. Decide where you want the tank to lie on your shoulders. Cover more over your shoulders with a wide strap that goes almost to the seams of the sleeves or opt for a thinner style. Draw the outline of your tank sleeves with a piece of chalk (you may need a friend to draw the back lines on). Decide if you want to keep the neckline where it is or alter it. If you like where the neckline sits, keep it as is. Create a lower neckline, or shape it into a V, by drawing an outline with chalk on the top of the t-shirt. But remember, if you plan to hem you'll need extra material to fold over so leave yourself at least 1/2 an inch of extra material.

Take the shirt off. If you don't have someone to help you to draw the back chalk outline, draw them on now using the end of the front lines as your guide.

Cut the shirt at the chalk lines. If you're happy with a distressed look, you're already done with this simple upgrade.

If you've chosen to hem the shirt, turn it inside out. Place your shirt on the ironing board with the front facing up. Line the edges of the cuts with the iron-on tape, moving it in enough from the ends to completely fold the fabric over it. Fold the edge of the fabric over the tape so that you can't see the tape anymore. Iron over the folded piece of fabric. Repeat this process for any other areas that you want to hem.

Put your new tank top in the wash, keeping it inside out. Wash and dry according to care instructions.
