Sprucing oneself up is a phrase that refers to making oneself look more attractive or presentable. It can involve activities such as preening and primping. Preening is the act of tidying one's appearance, such as brushing one's hair or straightening one's clothing. Primping is similar to preening but involves more elaborate grooming, such as applying makeup or styling one's hair. Together, these two activities can help someone spruce themselves up and look their best.
