A subject close to my heart due to recent travels. Here are some links, ponderings and possible (tongue in cheek?)solutions.
I used to be the girl who packed 7 pairs of shoes for a week's holiday - well no more... I can now make do with a pair of boots, some smartish flats for day time and some evening shoes. However, if I wanted to pack even lighter on the footwear front, there is a (truly hideous) answer out there - quoted as being "...fashionable women's footwear with interchangeable tops to create many pairs of shoes without having to pack them all..." "Why pack five or six pairs of shoes to match your outfits, when you can pack ten or fifteen different looks with a single quality sole from OneSole. Simply snap on an appropriate "topper" matching your outfit and pack ten times the quantity of shoes in a fraction of the space" Yuck.
I recently decided to buy myself a walk-on wheely suitcase for short trips and made the same mistake I always make with luggage - I bought something attractive with fancy leather trim and a satiny lining, but it's COMPLETELY non-functional - this is it in the photo it topples over on bouncy pavements, nothing fits in the outside pocket.. I could go on... When will I learn, just-fork-out-for-a-Samsonite-for-god's-sake-woman....
Perhaps I should have read this link first which provides some useful if slightly geeky advice on choosing a bag: http://www.onebag.com/bags.html
Rolling or folding? For me rolling wins everytime - partly due to my pathological fear of folding :-).. plus it's quicker, things get less creased and for some reason more fits in.
Another bad taste item I'm afraid. For the truly lazy (and unstylish, un-embarrasable etc); disposable travel knickers. Yes, that's right wear-n-chuck-out panties that go by the name of 'OneDerWear'
