Khloe Kardashian finds it a "little nerve-wracking" modelling swimwear next to her sisters.
The 27-year-old star feels uncomfortable showing off her curvy figure in swimsuits and lingerie alongside siblings Kim and Kourtney while shooting campaigns for the trio's Kardashian Kollection.
She told People.com: "It's always really fun working with each other. It's also a little nerve-wracking being next to Kourtney and Kim in lingerie or a bikini."
However, Khloe – whose weight has fluctuated over the years – recognises the benefits of displaying garments for their collection in three different sizes thanks to their varied body shapes.
She added: "That's the blessing of having a line that's designed by three different body-shaped women.
"I have things that are designed for my body, for a bigger curvier body. Kourtney has things designed for a petite body and Kim for a petite voluptuous body."
Khloe has previously admitting being envious of Kim's figure and has expressed a wish to trade bodies with the 31-year-old brunette.
She explained: "Kim, who I think is flawless, is always complaining. She complains about cellulite and I tell her, 'I'll trade your cellulite for my love handles!' "
