The first one I simply added on to the sides and put on some fabric buttons. I like my everyday shirts loose and shapely. I took my favorite t shirt laid it underneath to see how much i wanted to add. Cut the sides all the way up to and including the sleeves... sew... And Ta-Dah!
The next one i added 2 black and white pattern triangles to the front and 2 to the back. For this one i made a triangle pattern the size i wanted. Then i cut 2 slits in my pattern, from the bottom of the triangle almost up to the point, so I could stretch the triangle for a little flair. Laid it on top of my material, cut and Then top sewed it ... and another Ta-Dah!
The final one I added to the sides and added rolled roses for deoration
