More often than not, Kendall Jenner and Bella Hadid are the only two people who seem to know what's trending. Whether it's Kendall's affinity for sheer rompers, the supermodel's love of tracksuits, or simply a shared pair of enormous sunglasses, these fashion darlings have been quietly dictating the past few years' most influential trends.

To be fair, as sisters and "best friends forever," they do have a lot of the same stylistic influences. Welcome to the competition between fashion's most famous nepotism dolls: Bella Hadid and Kendall Jenner.

When the ingenues of reality TV aren't opening shows for Givenchy and Jacquemus (or working as the creative director of FWRD), they're influencing the masses with their eagerly followed wardrobes, which have sparked divisive movements including 2018's preference for tiny sunglasses and last year's embrace of the cardigan vest.

On Monday, Hadid was captured in London wearing a very English ensemble: a tracksuit with "LONDON" across the chest. The outfit didn't fall short because to the cuts and some strategic accouterments, as evidenced by the massive pants, lug-soled boots, and leather motorcycle gloves.

Meanwhile, Jenner opted for a big blazer, which she covered with a crisp, equally big button-down. On the bottom, the model kept things simple with a pair of straight-leg jeans and high boots.

The business casual style represented shades of Carolyn Bessette-Kennedy, while Hadid's get-up was Sporty Spice for the Generation Z. Similitude aside, the controversies sparked by the two 'fits have long been debated: little shirt, big pants or big shirt, little pants? The issue of style continues to rage on — oversized on top or bottom?

Both have their advantages. Bella's baggy clothes exude natural ease, while Kendall's big coat lends a businesslike air to the table. However, given Hadid's recent string of style triumphs (the odd bedazzled crochet hat! The cargo skirt! The furry earmuffs!), we have to give her credit.
