Here is an example of the user interface and prototype for a site which I have recently finished for the Southport Bridal Outlet. The brief was for a simple clean interface with a Sans Serif font (Roboto) without any unnecessary clutter.
Just to gauge the overall look and feel I built a prototype in Adobe XD to get an sense of the layout and to see which colours worked best with the interface. The finished site remained quite faithful to the original layout.
