Things You'll Need
Plain, boring T-shirts are items that everyone has in their closet. Before you throw the tees away because they're too big or blah, you may want to alter the T-shirts into something sexy. You can modify a plain tee numerous ways, and you don't even need a sewing machine. One style lets you to create a shirt with ties all up and down the sides, while a second look is a shirt with a scoop neck, rounded bottom and a criss-crossed lower back.
Tied Sides Style
Lay the T-shirt on a flat clean surface so the side seam is visible.

Cut the side of the shirt where the seam is located in a large triangle. The triangle should start about four to six inches (depending on how large the shirt is) wide on the bottom and get smaller as it goes up. The top section of the cut should be about 1 inch thick. This cut should go up the seam and stop about 2 inches below the armpit of the shirt.
Cut the second side the same way. Put aside the cut fabric for later use.
Cut 1-inch slits numbering about six to eight on one side of the newly cut triangle hole. Cut corresponding slits on the other side of the triangle hole. Make sure these line up with the slits on the opposite side.
Cut the slits in the second side of the shirt in the same manner.
Cut the excess fabric into 1- or 2-inch strips for the number of slits you created. For example, if you made eight slits on each side, you need 16 pieces of fabric.
String the fabric through the two corresponding slits and tie it in a knot. Complete this for all remaining slits.
Criss-Cross Back Style
Lay the T-shirt down face up.
Cut along the bottom seam of the shirt going up on the sides to create a rounded-edge effect. Depending on the size of the shirt, the highest point of the cut should be about 3 inches from the bottom.
Cut the neck of the shirt to make a scoop. Start about 1 or 2 inches from the shoulder seam (depending on the size of the shirt). Cut all the way across in a scooped shape. Continue the scooped shape on the back part of the neck as well, so it is even.
Flip the shirt on to the back side. Cut a square out of the back of the shirt, starting about 6 inches below the scoop neck.
Cut the fabric from the square into a thin string. Start at the bottom corner and continuously cut around the square like a swirl. Ribbon can be substituted for this step.
Cut four slits of each side of the T-shirt surrounding the cut-out square. The slits should have a corresponding slit on the opposite side.
Take the T-shirt string or ribbon and thread it through the holes, criss crossing back and forth. Tie a bow or knot at the bottom.
