It’s the perfect combination of serious and sexy. Celebrities have figured this fashion rule out: you don’t have to sacrifice style when you’re dressing up for business! Whether it’s for a day of meetings or an appearance on a red carpet, rocking a plunging suit is always the perfect choice. Many celebrities spice up the look by wearing a tiny bra top underneath — or even nothing at all! It’s an effortlessly cool ensemble that looks good on everyone.

Here you can see Kourtney Kardashian wearing a plunging suit at the 2018 CFDA Fashion Awards. The KUWTK star shined in a plunging suit decorated with glittery dots, giving off the look of a night sky. She accessorized with layered long chains and kept her hair back in a classic updo.
