Kim Kardashian Flaunts Baby Weight Loss in Skin-Baring Gown During European Fashion Tour

Kim Kardashian West has hit her pre-baby goal weight and she isn't letting anyone forget it!
The 35-year-old reality star is currently on a très fashionable tour of Europe, with her most recent stop at the Vogue 100 Festival Gala in London, England, on Monday. Kim donned a sheer Roberto Cavalli silk and tulle gown that showcased plenty of cleavage for the Kensington Gardens party.

Kim is basically treating the U.K. as one giant runway, slaying every red carpet -- and sidewalk -- she hits. Like, the de Grisogono party in Cannes, where she rocked blinged-out chainmail.

She went casual on the streets of London -- well, Yeezy-casual -- with Kanye West, but lest you think the outfit is too subtle, she paired it with a giant, gold necklace that said "SEX."

Hey, Kanye. Eyes up here.
The Keeping Up With the Kardashians star then returned to some sparkle and shine for Vogue 100 Festival: Fashion, Friendship and Fabulous Lashes at the Royal Geographical Society.

If you're not catching a theme, then you must be blind, because that theme is C-L-E-A-V-A-G-E. And if that doesn't spell it out for you, this shot of Kim leaving the Vivienne Westwood Couture shop in London is worth a thousand words.

Oh, the premiere of La Traviata at the Teatro Dell'Opera in Rome, Italy? CLEAVAGE.

Even her most demure, covered-up ensemble of the week -- worn out to C London back in England -- featured enough mesh accents to show off that CLEAVAGE.

When ET caught up with Kim in France, she gushed that Rob will be a "great dad" and revealed Kanye gives parenting advice. Find out what else she had to say in the video below.
