I often see the le pliage recommended on here so have been looking at them online. Are they really worth the money for what they are? I do like the look of them and the small tote with shoulder straps is the right size/shape for what I need, but £50+ for a nylon bag seems crazy to me. Also, if I do go for one, would a light colour be a really bad idea? Do they get marked/dirty easily? Can they be washed in any way? Thanks.
