Everyone knows not to use white to a wedding event for worry of resembling the bride, however there's no method of making certain you won't be in a similar or - God forbid - the very same outfit to another wedding event guest.
So spare an idea for the 6 guests who reached a wedding event in the really same gown over the weekend.
The gown in question was a navy and blue number from Australian clothing brand name, Forever New.
It's called the Debbie Lace pencil dress, and costs $159.99 (₤ 95).
The funny turn of events was taken in good spirits by all involved, and has actually provoked much amusement online after one of the guests posted an image on Facebook.
" You truly should start a bridal pc registry so that your consumers can enquire whether anyone else has purchased among your dresses for the same occasion," Debbie Speranza wrote on the Facebook page of Forever New, with 3 "weeping with laughter" emojis.
" No we are NOT the bridesmaids just the guests - think I are worthy of a present voucher for all this ad," she joked.
Whilst some people commented saying the scenario would be their "worst nightmare," the bulk discovered the photo amusing.
" What a laugh!" a single person composed. "But what did you state to the guests wearing something else? Did they feel like they 'd missed the message?"
And some ladies even exposed they had - or had actually almost bought - the exact same gown.
" Wore this dress on the weekend," one female shared.
" Was this the one you simply bought?" another female asked her pal, who responded: "Oh what !!! Yes it is! Amusing, hope this does not happen to me."
After that Zara gown and coat, it's clear the ladies of the world have a thing for blue.
