This point I don't see as a negative. Phoenix book is very wearable when you want something basic that you won't have to make an effort to accessorize or fuss over figuring out how to wear/use the jacket. It's like comfort food. Basic but satisfying.
I see this book the same way the Riviera book was. Not the same weight or finish of cloth as Riviera but serves the same purpose for me.
Basic cloths/patterns with enough subtle nuance to not be pedestrian. The stuff that is easy to mix into a wardrobe and gets worn a lot.
This is all about personal taste so if you like Phoenix then have at it. When I say it's uninspiring I mean that the colors strike me as dull and lifeless and have a chalky appearance. And I wouldn't call it a book for basics - there are some pretty extreme patterns in there (the pinks for example), many of the solids have a second color flecked throughout (many times black) and a lot of the standard colors are varied shades (see the tan, for example, which is pretty orange). Again - personal preference, but I usually think of w bill as the best in a given range - the donegals, Harris tweeds, linens and lamlana strike me as top in their category - but for 10 oz worsted wool I think there are better choices. Caccioppoli/drapers do it better.
