Giving a new look to something can mean transforming it into something entirely different, refreshing it, or simply updating it. Antonyms for this phrase would include leaving it as is, neglecting it, or abandoning it. When we don't give a new look to something, we are missing out on the opportunity to bring new life and vitality to it. By neglecting something, we risk it becoming outdated and irrelevant. While not every object or space needs a complete overhaul, some level of maintenance or refurbishment is often necessary to keep things fresh and functional.
