A feather in your cap
English idiomatic phrase
The term a feather in your cap is an English idiomatic phrase believed to have derived from the general custom in some cultures of a warrior adding a new feather to their headgear for every enemy slain.[1][2] Or in other cases from the custom of establishing the success of a hunter as being the first to bag a game bird by plucking off the feathers of that prey and placing them in the hat band.[1][3] The phrase today has altered to a more peaceful allusion, where it is used to refer to any laudable success or achievement by an individual that may help that person in the future.[4]
