I too am guilty of being over 6 feet tall and wear a size 13 (mens). I had this question go through my head a few weeks ago and did a brief search for actresses 6 feet tall and over. Then broadened the search to include non-actresses. I felt at ease after reading names (a few are listed below). None-the-less, if they can "pull it off" with makeup, you\we can also.
Geena Davis, Gwendoline Christie, Brooke Shields, Aisha Tyler, Brigitte Neilsen, Famke Janssen, Jane Lynch, Jordin Sparks, Kristen Johnson, Tilda Swinton.
I guess the point is to focus and accentuate other areas to even out the view or draw a viewers eyes from the obvious. Now I just have to plan and work on making that a possibility for myself also.
