what do you want to see on the website? how do you get to feeling comfortable buying a bag you have never really seen? what questions do you ask the seller?
What kind of sites are you referring to? Shopping at a department store's online site vs. small boutique online site vs ebay vs shady sites selling so-called authentic bags for cheap are ALL very different experiences.
If you've never seen a bag, make sure the site has a solid return policy. You can also check here for threads about certain retailers, to hear about others' experiences with them.
I would never buy a bag I haven't seen, felt adn tried on from an online store
So it would HAVE TO be a bag I've tried on at an amazing price w/ stellar customer service
. . . all reasons why I haven't been able to buy a bag online
I've had outstanding service with: Luna Boston; Active Endeavors; MZ Wallace; BLVD; Linnea Pelle; Net-a-Porter; and ELuxury. Not that many others aren't good also, I just have personal experience with these.
