In one sentence, describe what the following article is about:

Button up the majority of the buttons so the shirt will hold its shape and stay together while you fold it. Run your hands over the fabric to straighten out any wrinkles or creases, then adjust the collar until it lays flat and neat. Use a clean, flat surface such as a table, dresser, or bed as your workspace for folding. Lay the shirt facedown carefully, smoothing it out and adjusting the collar if it has folded or collapsed. Start the fold at the shoulder and bring the left arm across the back of the shirt. This will make the left side of the shirt one long line. The goal is to turn the shirt into a long rectangle shape, so make sure that the cuff on the left arm doesn't extend past the right side of the shirt! If the arms are extra long and extend past the edge of the shirt, fold the cuff backwards so it stays within the rectangle. Now that you've mastered the left sleeve, do the same move with the right sleeve! Fold the right arm in at the shoulder and bring it across the left arm so they cross in the center of the shirt. Once again, make sure the right sleeve doesn't extend past the edge of the shirt. You can always fold the cuffs back in if they extend past the sides of the shirt. Fold the bottom third of the shirt up, then fold the next third up so it meets the shoulders of the shirt. This creates the perfect size for placing the shirt in a suitcase, drawer, or shelf. Straighten out any wrinkles and make sure the collar is neat before packing or storing your shirt. This technique will help protect the collar from being crushed and the fabric from wrinkling too much. Although this technique protects your shirt from excessive wrinkling, you may still notice a little wrinkling from the folds. Just keep in mind that the next time you wear your shirt, you may have to do a bit of steaming first!

Summary:
Button up and smooth out the dress shirt. Lay the shirt out facedown on a flat surface. Fold the left sleeve in toward the center of the shirt. Bring the right sleeve across the left sleeve to complete the rectangle shape. Start at the bottom and fold the shirt up in thirds. Flip the shirt back over and adjust the collar.
