Cut the end of t-shirt off....hem the raw edge.....Ta-Da the extend a tee you see on TV for 20 dollars!....now FREE!!! always a plus. I have a huge clevage (home grown, not silicone), and lots of pretty tops simply do not cover the opening. Too hot here in the South to layer and on my size body too bulky. This is perfect, just move it under the arms and I am all covered.
