"It was the worst feeling, but I just kept wearing it because I just thought it was what you're supposed to wear," the Strong Looks Better Naked author explained. "I even remember my mom asking me what was wrong and I was too embarrassed to say. I was 13 -- I shouldn't have been wearing a thong!"
While Khloe did not go on to explain who was stuffing the Easter eggs at the Kardashian house – or why they were including thongs as gifts for the teenage Kardashians -- she did share a few of her other firsts, including her first expensive designer item.
The reality star recounted how she received a Prada handbag from her mom for her 13th birthday -- the same age she'd be when she discovered a thong in a plastic egg. "It was the first time I was allowed to have anything designer and I remember thinking that bag was the coolest thing ever!"
As for Khloe’s first pair of pricey shoes, those didn't come until she was 16, when her dad, Robert Kardashian, bought her a pair of knee-high Dolce Gabbana boots. "They had safety pins all up and down the back and were so punk rock," she wrote. "I still have them and would wear them to this day. They remind me of him."
