I ended up making two tops and a dress and since the dress is my favorite dress now, I figured I could show you how to make it!
Lay the "body" of the T-shirt flat on the table. Draw a strait line just under the neck of the shirt. Use a tape measure to measure from the bottom of the T-shirt to make sure the line get strait! Carefully cut the top part off both front side and back side. It is important that this cut is strait or you will end up with a dress that is uneven.
Cut the sides of the dress to a fitting shape by using an old dress as a pattern or by simply try it on. Make sure to leave and extra 1 inch on each side for the seems.
Pin the sleeves to the top of your "dress" with the outside of the fabric facing each other. Sew a strait seem, remove the pins and repeat on the back side.
Finally sew the sides of the dress and try it on to make sure it fits.
From here you can be creative and add ribbons, fabric flowers, beads, strings for halter neck...etc, etc...
Hope you will succeed and let me know if you have any questions! ;-)
