This phrase carries a negative connotation, implying a lack of self-control, discipline, or effort. While it primarily pertains to physical appearance and personal grooming, it can encompass a broader range of behaviors and attitudes.

In popular usage, "let oneself go" typically implies a decline in one's appearance or physical upkeep. It could manifest in various ways, such as a decrease in personal hygiene, disregarding fashion trends, or gaining weight. This idiom is often used judgmentally, criticizing the person for failing to maintain their previous standards or meet societal expectations. However, it is essential to approach the usage of this phrase with sensitivity, as it can be hurtful or offensive when directed at someone's personal appearance or behavior.

Furthermore, "let oneself go" can extend beyond physical appearance and describe a decline in other aspects of one's life. It may signify a lack of motivation, surrendering to bad habits, or giving up on previous achievements or ambitions. In these cases, the idiom suggests a relinquishment of control and a resignation to a less desirable state or condition.
