Gap 4 button vest size medium mens

I’ve had some good times with this vest but atlas it is too small and ready for a new home. This vest has a navy blue front with subtle gray stripes. The back is dark gray. Two pockets for storing small items. About Me: I’m 5’7 and weigh 194. I can put the vest on and button it however it clearly looks too small on me. From a pet free smoke free home.
