To wear this Phoenix navy vest top, simply put it on over your upper body and tie the self - tie waist to your preferred tightness. It looks great with the matching trousers for a monochromatic look, or you can pair it with other bottoms like jeans for a more casual style. When it comes to care, check the label for specific instructions. Generally, it's best to wash it in cold water with a gentle detergent. Hang it to dry to keep its shape. Avoid ironing directly over the gold buttons to prevent damage.
