Value is a very subjective term. I don't buy anything anymore unless it has value. Having said that, I still buy Armani, although not as often as before, and there are certain items of theirs that i won't touch (knits, shirts, suits).
Three years ago, almost everything I bought was Armani. Having now been educated by the forum, my tastes have changed immeasurably towards high-quality and hand-made goods. I'd never buy another armani suit, but I bought a really gorgeous black wool & angora overcoat this year. The fit is absolutely perfect (very slim) and I think it's worth every penny of the 2.5k (cdn$ with taxes) that I paid for it.
For casualwear, Armani still kicks ass in the pants department. I've got ~10 pairs of flat front, creaseless pants in my closet that I still wear quite often, even though I did a big transition to Borrelli jackets and MTM pants with an incotex cut. Average price? Probably $350 cdn. Cheap? No. Value? Yes. Btw, I've had most of these pants since 2002 and they still look great. Their shirts and knits are absolute garbage though. Even when I like their sweaters for instance, I won't buy them anymore because i know they don't last.
My worst purchase was the black MTM Armani suit I bought before I knew any better. I brought it with me to a wedding a few weeks ago and when I put it on to go to the reception, I couldn't believe how bad it looked. The shoulders were kinda lumpy and the fit just wasn't as I remembered it, or maybe I'm just more picky about fit these days. Regardless, I took it off and changed back in to what I had been wearing for the actual ceremony (borrelli jacket and incotex pants).
Every time I look at that suit I now think what a waste of money it was. I don't think that when looking at the pants or overcoat, however. GA is like any other designer, they make some nice stuff and some crap. They still produce some knock-out items imo. I bought a pleated silk & wool scarf this winter that is absolutely gorgeous. Although I felt the pain of the 450 it cost, it puts a smile on my face every time i see myself in the mirror wearing it. And I know I have the only one in montreal :P
