Hollister Co. offers the young look of Abercrombie and Fitch. I used to love the clothes back in the US. They might be slightly expensive, but the quality definetly pays off. The outside look of the shop calls one's attention... one travels to California.
The inside is quite cozy. One may find some armchairs before the cashier with many surf magazines. It smells like perfume everywhere, I've seen them spray it all around. I don't like the music, it gets too load and becomes a little annoying sometimes.
One of my favorite items is their tanks. There are so many color to choose from and they last long too (about 3 years or so).
The jeans are also great. They really make you look in them, they hug your waist :)
There are different types of jeans: skinny, supper skiny, bootcut...
They also have cute jackets with very nice patterns. This is one of my favorites too :) The flowers on the back look spectacular with a white shirt as you can see on the pics below.
Other handy items are "layer-shirts". You can wear them with a colorful tank underneath and you'll get the layered look. It is very usefull and allows different combinations.
I recommend it. However, I hope they addapt some of their policies in other countries, respecting their culture :)
