This will happen in your peer group. Although most young ladies are heavily attracted to the kilt, there will be some who will be a bit surprised/shocked to be actually up close and personal with a kilted man. You have the good fortune to be both tall and and enviably lean. Part of the reaction is that you dress up the kilt by being obviously quite comfortable in it. Whether you top the Cunningham with the T-shirt or the sweater that is in your avatar, it will look great on you. Now do yourself a big favor and not grow out of the kilt. ( Sorry Nick).
The wrinkles in your cheeks give away the pride and enjoyment that grandmother's work has set on you. Even in the pleat picture the mirror shows the glow of pride. Treasure this as it will help you through any dark times ahead.
