If you are going for one of the safest online shopping site, go for myntra.com. It has vast variety of dresses for both men and women. Everytime I bought any dress from it, I got it on day estimated by the website. Although there are some queries about the misplaced or wrong items but they were very well handled by myntra. Even if you want to replace or return any item, you wont have any problem you will just have to hand over the courier to their courier partners. On comparing the product’s price from other websites, it varies as sometimes you can get that item from other site with lower rates so this is the point of concern. But if you are going for it, your money wont get wasted.
