I was so caught up in the Zara drama that I missed this thread, Sveta. Of course you can use a couple of extra pairs of pants in your wardrobe; we live in Canada and wear pants nine months of the year.
Both of those pairs look great on you and I also like Suz's way of handling the one-in, one-out issue. Cut the tags (including the size ones if they bug you), and wear those pairs to death this fall and winter.
And, by the way, I recently showed a couple of your WIW pictures to my sister who wears the same sizes as you do and who has a very similar body shape. She was also feeling a bit disheartened because of some of her recent shopping experiences. Her first reaction was to dismiss you as just another model. Once I convinced her you were just a extraordinarily striking, well-dressed, "normal" woman, she wanted to see more and more. I think I called you "the fabulous Sveta" in your other thread. You are exactly that--and a total inspiration for all of us who need that XL in Zara.
