in there like swimwear

(UK, Irish) the garments that one wears when bathing in the sea or a swimming pool, especially the one-piece garment worn by women and girls.

(UK, slang, obsolete) To cheat or victimize.

Slang for something that's completely secured, locked down, and guaranteed — as in a deal, a victory, or a situation that's already settled. When something's sewed up, there's no doubt about the outcome: it's done, it's yours, it's in the bag. Common in AAVE and hip-hop culture, it's the ultimate expression of confident certainty, whether you're talking about winning a contract, closing a deal, or dominating a competition.

(UK) Having a good chance; likely to succeed.

(Australia, vulgar, informal) To win or achieve something easily.
