Babes In Tube Socks, Guess Who For National Sock Day

It's National Sock Day ... so, it only feels right to celebrate with a little guessing game. Can you figure out which smokin' babes are rockin' tube socks in the following pics???

A number of famous ladies have made the sporty footwear a fashion statement ... including supermodel Bella Hadid, actress Gabrielle Union, and Swedish stunner Elsa Hosk, among others.

Just take a look at "The Valley" star and "Vanderpump Rules" alum who paired her long legs with '70s-style booty shorts and a vibrant yellow tank top. If you can't figure out which of the many 'VPR' hotties this beauty is, here's a hint ... she recently announced her pregnancy.

Now take a gander at these golden gams ... belonging to a different reality star from "The Bachelor." This lady famously walked away the winner of her season of the dating competition ... and remains one of half of a "Bachelor" success story. She's also a mom of 3.

Any guesses???

This bikini model knows how to keep things sizzlin' ... and often brings the heat to Sports Illustrated. She gave a closer look at her killer body in a matching Calvin Klein underwear set ... rounding out the look with some Adidas tube socks.
