Creative Postcard Creation using Adobe Illustrator

I need one side of a postcard created in a creative and visually appealing way. The business is a tailor shop, and we are focusing on Alterations for Men and Women. The postcard needs to be very classy, with nice visual effects, and needs to be created in Adobe Illustrator preferably. The final file should NOT be in outline mode and should be editable. Creativity, classiness, and aesthetics are very important. I will provide all images and dimensions, the illustrator file is already started. It should be 6.13 (H) x 8.33 (w) with a 1/4" bleed. Please see attached PDF as a starting guide.
