Kim Kardashian took to her twitter account to promote sister Khloe's DASH store by posting pictures of herself wearing clothes to be sold at the store.

Kim Kardashian made her usual dramatic entrance to her Miami hotel on Thursday alongside sister Khloe while wearing a black high-low dress with sheer maxi train and patent leather heels. The most famous Kardashian, who turns 32 later this month, hid most of her curves beneath the bellowing sheer fabric while her 28-year-old sister kept thing simple in a white t-shirt, red trousers, and black heels.

The mini-mogul spent her afternoon tweeting images from the sisters' Dash store of herself in a Flashdance-inspired shredded t-shirt and kneeling near the nail polish section.

"Wearing "Kourt's Ready For A Pedi" from Nicole by OPI sold at DASH," Kardashian helpfully tweeted to her 16.3 million followers and future customers. The Keeping Up With The Kardashians stars' new dress collection, exclusive to Dorothy Perkins, will be released in the UK in four weeks.

TMZ reported that Kardashian and Kanye West are ready to move in together and are currently house hunting in Miami. According to reports, West was even caught on camera holding a umbrella for his lady love while the two shopped for their perfect love nest.

"K&K have been talking about getting their own place for a couple of months and believe Miami is the perfect location because they both love the city," a source told TMZ.

After the day of real estate hunting, the pair settled down for a meal at Prime One Twelve. Following the busy day, Kim hit Twitter to note, "Miami fun day with @kanyewest."

The 31 year old star and her beau have decided to join forces and launch an all new fashion line. Talks about the collaboration are still in its initial stages but sources have confirmed that the process is on.

"Kanye and Kim have figured out that if they combine their names it could be big business," the Sun quoted a source as saying. "They've both got massive fan bases who will buy their gear.

"It's also a sign that they're in the relationship for the long haul and that they think it's a romantic way to seal their relationship," the source said.
