The reality TV star and her sisters, who also have their own accessories line will launch beach outfits, 'Beach Bunny Swimwear' which feature gold hardware and side-ties, Contactmusic reported.
"I love getting glam and dressed up when I go to the beach and side-ties fit my body type the best," Kim said.
Kourtney, who gave birth to her first child in December wanted to make her swimwear practical because her figure has now changed.
"I wanted amazing bikini that is super easy to wear, but has extra support on top-since I now have that issue," Kourtney said.
The range will be available from next month at beachbunnyswimwear.com, at a price tag of USD 175 and under.
