The socialite, who raises son Mason with partner Scott Disick, explained that it would be easier if she moved to Manhattan.
She told Cliq: "We keep going back and forth. Scott has had a place in New York since he was born, so we go there a lot.
"Now that we have a store in New York, we have a reason to go back. I'd love to be bicoastal."
Kardashian added that it's easier to get around in NYC "because you don't have to take a car and can hop out and take the subway.
"If I want to go somewhere far and want to take Mason, it's just hard with a car seat in a taxi."
The 31-year-old then talked about her NYC 'DASH' boutique and the problems she faced with the new store.
She said: "It was so hard to find the location, rents are so high. There was definitely more pressure to have great merchandise. There's just a different consumer.
"Miami is flip flops and jean shorts. In New York, it's all about fashion. Our store was three times the size, so we had to order more merchandise.
"In New York, after the second day we had to order another cash register and it was harder to find employees. I thought Kim wouldn't have been as helpful in New York, but she was."
