Preferably buttons.

Buttons have to be my favourite fastening, I'm not quite sure why, they just hold an attraction for me. These are closely followed by buckles dependant on the weight of fabric being used. Then comes  poppers, especially if they are decorated with a button. Next up are zips, as long as they concealed and fit with the lines originally created in the garment and finally Velcro...eugh Velcro, itchy-scratchy-fails-to-perform-fluff-grabbing Velcro. How I despise you Velcro. That may have seemed like an unnecessary post, but I have been finding that my choice of fastening significantly changes the design qualities and market level of a garment. I will be interested to see how this effects my final collection.
