I am very happy with my new waistcoat. It is a little longer in the waist, but that is because my trousers sit lower than the men's due to my leg curves and I needed the waistcoat to cover waist padding and sit over the trouser waistband.
While the waistcoat is not visible, I was wearing it at our 150 yard standing shooting practice day at Monarto Rifle Range. This was a great way to spend the afternoon, even if I spent the day as official and scorer, instead of shooting. The men did an amazing job at that range, especially as two members had not shot before.
