Ditto much of what has already been said.
Here's a thought...
Why not turn this around and have Dame Doris focus instead on the positive? Give us tips, photos and commentary on appropriate (as in comfortable & tasteful) outfits to wear to WDW. Try providing useful information on park fashions, such as where to find comfortable walking shoes and sandals that look good too... or nice, neat clothing options like capris and skorts that will allow one to keep cool & comfy while still looking nice and thoughtfully put together.
I think you will find that people are more receptive to receiving tips on how to dress well, and seeing photos of really nice fashion choices. Dame Doris could even take it one step further, and search out online clothing sales items which are similar to a chosen 'Perfect Park Outfit' each week. Inform us, and help us to find those great apparel options to wear on our next visit to WDW. Rather than being so critical of people's fashion faux pas, why not make Dame Doris's column a fun and informative place that can help us to prepare for our Disney vacation.
