Here is how you can make a no sew and easy stylish T shirt. To create a no sew halter top from your old T shirt, start by laying the T shirt down and then turning the shirt inside out. You would then cut off the sleeves near the arm and then you would cut across the back of the T shirt. Then lift the flap of the shirt and cut right to the neck area of the shirt. Then you want to cut the excess straps off the created halter top and then you have created your new halter top.
