Pippa Middleton, the 34-year-old sister of Duchess Catherine, caused an online frenzy when she arrived at Prince Harry and Meghan's wedding ceremony.
Pippa and her husband, James Matthews, were among the 600 wedding guests who gathered at St. George's Chapel on Saturday morning.
She wore a pale green silk dress with a pink floral print and the feminine dress complimented her figure and showed off her growing baby bump.
However, it shares a striking resemblance to a can of Arizona Iced Tea. The beverage comes in a pale green can with a pink flower design.
Sarah Rogers, the director of photography at the Daily Beast, tweeted a comparison image of the dress next to the beverage, and it soon took the world by storm.
Her tweet had been liked more than 20,000 times and Twitter users rushed to the social media platform to share their views.
Ritas, a company that sells 'margaritas in a can,' posted another image of Amal Clooney in a striking yellow dress, next to a can of Pine-Apple-Rita.
Despite the resemblance to the alcoholic beverage, Amal stole the show and made it to Cosmopolitan's Best Dress Wedding Guest list.
In another tweet, Ritas shared an image of Queen Elizabeth in her green dress, next to a can of Lima-A-Rita, and asked in the caption: 'honestly, what was this dress code?'
Hilary Sargent, who writes from the NY Times, kept the 'guess the beverage game' going and shared an image of the Priest next to a can of La Croix Peach-Pear Sparkling Water.
As reported by Simple Most, Pippa's dress can be purchased from The Fold in London for only $695. The dress is currently in high demand and will only be despatched between the end of May and mid-June.
