I have had a long waistcoat before, but never wore it as it would visually cut my body in half. So when I spotted this one I knew it will work as it has an upside down V. It’s like a half tuck build in. Also the original waistcoat had brownish buttons which would limit outfit options,  so as per usual I have changed buttons, so they match the fabric colour. Don’t be scared to adapt clothes to fit your needs.
