Wow and that was 2005 alone. Mind-boggling..
And the answer to the thread's question: Would I dress like her?
Well I would love to have her closet, about 50% is really really fab and certainly more than enough to fill my humble wardrobe. The rest can go to charity.
Would I use the pieces like Mary did? Well her mixing and matching is horrible at best and she has a completely different way of accessorizing (unlike anybody I know...) but the pieces, suits, coats and such are great.
Funny, how Aussiecro describes some of the outfits that I considered best as boring or bland.

But perhaps the more conservative business approach speaks more to hhm more mature people
(dear Aussie, of course I don't accuse you of being immature, I am just desperately trying to avoid the dreadful "old")
I like alot of her older 2005 era wardrobe too.

I think her first LiW influenced her clothing choices alot hence the more polished, professional look.
It's shocking how many of the clothes from that time have only been worn once. IMO it seems that when Countess Victoria was off the scene Mary/Anja had more input and resulted in the disaster we see today.
