My favourite departmental store is Lifestyle, kirti nagar. I go there usually during Sale. I buy my western wear from there and my kids jeans and shirts from Lifestyle. It offers a wide variety of national & international brands in clothing and jeans. Kids section is well arranged from infant to 12 years. It's highly recommended for all age groups. I mostly get confused so need to focus on a particular brand to end up shopping else one can end up getting puzzled.
