The Keeping up with the Kardashians star explained that she didn't enjoy her own pre-wedding celebration and is therefore considering a "payback" for her older sibling.
Khloe, who married Lamar Odom in September 2009, told E! News: "I had the worst bachelorette party. Like, it wasn't sexy at all, so I might just do a payback for Kim... Because Kim does not like what she gave me, like penis straws and a little go-go dancer. Kim would cringe if I did that for her, so I might do that just to see what happens."
Khloe also said that she and sister Kourtney have not decided whether to buy engagement gifts for Kim and her fiancé Kris Humphries.
"Kourtney asked me the other day. She's like, 'Do we buy her an engagement gift?' I'm like, 'No-one bought me an engagement gift!' What is that about?" she exclaimed.
The 26-year-old socialite said that she hopes Kim will have a Vera Wang dress made for her wedding like she did.
"She did mine, so I hope she does," she added. "Just because I love her, and I feel like when you think of weddings, you think of Vera Wang. I think it would be a perfect fit."
