Buy it or not?

When I shop for clothes I really don't usually look for the name brand, I only shop if they are on sale because I don't like to spend too much money buying expensive clothes because I know that later on I will just get bored with them and it will be stocked away in my closet, and besides I believe that the clothes will look good on you not because of the brand but because of the way it fits and how you wear it right? The other day I was browsing online and I felt so in love with the 3 dresses in the pictures below. I am tempted to buy them since the spring is already here. I think these are perfect dresses to wear. But I still can't figure out if I really want to buy them or not because when I seen the price each of these dresses I felt it would make a hole in my pocket because for me this is a bit pricey than the usual price that I am used to paying. Whew! I think I will just have to control myself a little bit, since I really don't need that many clothes anyway, but what can I do I am just a woman who happens to be like those thousands of other people that likes to shop.
