Bikinis and heels are arguably the most important suitcase staples for any TOWIE girl abroad, especially when they are due to go in front of the camera, so it's no surprise Danielle is horrified by her holiday faux pas.
Taking to Twitter after realising her error, Dannielle told her followers: "Gutted I left my @MonsoonUK bag with all new swimwear and shoes on my @British_Airways flight #SoAnnoying."
We hope you get them back, Dan!
Reality star Danielle was among a handful of TOWIE cast mates who flew out to Tenerife this morning and they are due to start filming a special opening episode for series 14.
Along with Danielle, others picked for the trip include Billie Faiers and baby daughter Nelly, Gemma Collins, Lauren Pope, Lydia Bright, Ferne McCann, Jessica Wright and Bobby Norris, and the group have been keeping fans updated on Twitter.
Branding the holiday destination 'Tenners', Bobby tweeted earlier today: "Gatwick bound... #Tenners." Billie, meanwhile, said: "On our way to the airport with @fernemccann, mother and of course my little nelly noo..."
There's been no announcement yet as to when the series will kick off on ITVBe, but the turnaround is usually pretty quick. Yippee!
