Banana Republic sells products for women and men and accessories for all. On their website they also have a section for petites.
The pricing strategy is available for people who are opulent, this means the target audience may be for older people who have permanent jobs. Although it is expensive for some garments, they also use psychological pricing which makes your mind round up the cost, for example a belt would be £29.99 but you think it is £30.
The shop is located in Central London so it is effortless to find. It is also based on Regent Street so it is down the road from the Oxford Circus underground.
