yeah this is definitely an ongoing trend. the high streets were FULL of tiered dresses and skirts this summer. but it looks like this trend hasn't lost any momentum going into s/s 06.
I personally find the ferragamo ones quite ugly...I don't like the look of lots of short tiers. (the molinari ones may be an exception...as I like the edwardian references. it's a bit eliza doolittle which is kind of sweet) I prefer longer, more subtle tiers. the jessica odgen ones are adorable. I have a dress with long, chiffon tiers and it's actually really lovely - very subtle and not flouncy in the least. floaty rather than flouncy. but like I said, it really all just comes down to the individual dress and how it's been designed.
