I've checked them out at DASH, les Kardashians boutique in Springs Soho, I personally liked the sequenced ones, they are more expensive but at least you feel that some effort was put into the design.
Since I mentioned DASH, well i was so disappointed not to see more Kardashian designs, except the tees, bottled water, candles and fragrance, the boutique is multi-brand, the choice of the 3 sisters.And yes people are still lining up to enter the boutique, on the door a huge bouncer asking them to take the line, once inside you feel that it is just another boutique, nothing shouting "Kardashian Style" except for few pieces that i wouldn't even try on, also on the middle wall of the boutique 3 big frames of their pictures, people usually take souvenir photos there or in front of the shop :)
