I need to feel the size properly, touch the material, and can't be arsed to make the reject every time and send back all stuff
I too have that feelings, so I did not buy the trousers online, because it's after some time I am buying trousers and my size has changed. However, once you know the brand and size, its ok to buy similar products online - from my experience, brand does matter a lot, as quality is based on brand.
