I would call myself a crazy online buyer.:) But I’m not at all lose my mind. I buy the stuff that really worth to buy and not regret any of my online purchasing experience ever.
The same clothing that in the malls and onlines should be varied greatly in the price, so why not pick the cheap yet with the same quality. It requires a little enegy to pick out the good online store anyway since there is certainly many liars out there onlline.
You need to know your body size well to buy suitable clothing online. No blind buying 
Pants is the hardest to buy, but I have been sucessuful in buying one nice boot cut pants, so it greatly boots my enthusiasm to online shopping.
Up to now, my online shopping clothing experience has been very sucessful and I was more and more loving this way of lifestyle.
