As any woman who's tried it knows, showing cleavage can be tricky. And, as a pair of stars at the Golden Globes demonstrated, the task can be trickier for some than for others.

Exhibit A: The notoriously skin-baring and buxom Mariah Carey -- who walked the red carpet with husband/umbrella holder Nick Cannon (10 years her junior) -- donned a Hervé Léger by Max Azria curve-hugging long black dress with plunging V-neckline, putting her business front and center.

Unfortunately, with the 39-year-old "Precious" star's breasts being so out there, it was easy to miss the fashionable elements of her ensemble, including diamond and platinum chandelier earrings by Chopard, a stack of diamond bracelets and the totally on-trend power shoulders of her bandage dress.

On the flip side, 43-year-old award ceremony presenter Halle Berry took the plunge in a Kaufman Franco silk bias cut gown with lace inserts that was actually cut lower than Carey's Léger look and quite similar in style, yet the actress managed to look sexy, not sleezy.

The difference? Berry has a smaller chest and therefore less cleavage, so her girls were under control and she avoided giving off a desperate "check out my goods!" vibe.

But maybe it's just us... Who do you think flaunted her, um, gifts best? Leave a comment.

And see which bold dress color dominated the 2010 Golden Globes.
