Givenchy is just awful. Too bad, really, because I like the way some of their bags are styled. Their clothes are absurdly-priced, as well: $900 for a printed cotton shirt that's made in Portugal?
This wasn't the case a few years ago. Our standards haven't changed, but prices for most brands have increased dramatically while quality has dipped or fallen off a cliff entirely.
Brands I own:
-LV: in my experience, very good quality and high prices, but most of my pieces are older. My mom bought an LV tote last year and the strap SNAPPED off just above the mounting hardware after only two months. The store manager refused to exchange it and insisted on a repair; mom only got her way after she sent corporate a nastygram.
-Hermes: my one bag from them is canvas Fourre-Tout tote, which cost under $500 when I bought it a few years ago. Very nicely-made and finished, but good luck getting canvas anything for less than $1k these days.
-Marni: love this brand, though few others do. I find the quality of their bags to be quite good, and their prices (relatively) reasonable.
-Gucci: one of my first designer bags. Quality is fair, though the fabric is wearing at one corner. Would not buy again, especially at today's prices.
-Valentino: nice materials, quality of assembly decidedly less so. Traded with Rach on this bag so can't complain about the price.
Have heard good things about Celine and Proenza Schouler, but get ready to pay up for the combination of nice styling and decent quality.
