I find this to be the best online shopping experience on the web. Every year I order all my business clothes, and some casual as well, from this department store. The sizes are standardised, which mean that once you know your measurements, every item in their shop fits in the same way. Also, the quality is excellent and the prices very cheap as compared to Australia (Recently I bought a pair of woollen trousers, made in England, for about $40 - the same item in Australia is $300 at Myer or David Jones [similar quality department stores]).
Shipping is free to Australia if you order over a certain price, and the best part about this service is if you need something quickly it gets here within the week. All items are packed beautifully, even including wooden hangers and suit bags for some items.
Their website is great, because it not only shows multiple views of the clothes, but also there is a video of a model wearing them, which means you get to have an idea about how the fabric moves when you walk (important when purchasing skirts, for example, and also you can see the fit of the trousers).
In addition, the quality is so good the clothes last 'years', and because they are mostly classic styles it is appropriate to continue to wear them [e.g. I find it good to have a new 'look' each year, but after 3 years of not wearing a set of clothes, then you can bring them back and people have forgotten!]
