I've picked up a few J. Crew items in the past few weeks and since most are still available I thought I'd offer some reviews.
The perfect shirt I already posted and CrazyOne has also reviewed it. Lightweight cotton in gorgeous colours -- it is brighter lighter than pictured and flattering to different skin tones as it works for C1 and for me.
The long downtown field jacket: I was in need of a very casual yet not "gear" coat for warmer weather. This is unlined waxed cotton that is good for light rain but not a complete downpour. It fits TTS; I have the XS and can layer under it. Lots of great pockets. The zipper is a bit hard to work (even with graphite applied) simply due to its being a two-way -- you know how those can be tricky to get going? Anyway, I'm getting better at it with practice. The green is gorgeous but I didn't want the gold hardware so went for the navy. The corduroy collar is really nice.
The striped cashmere tee. I'm a big fan of these J. Crew tees; I own a Collection version in a pink from several years ago (pictured also but sadly no longer available) which is slightly softer, but even the regular ones are pretty good with a cami underneath. This is my version of a tee shirt in winter since it layers nicely under a jacket or coat and can be topped with a scarf. The grey stripe is fun. I loved the green/ blue, too but decided the grey would be easier for me to pattern mix.
I'm also keeping the jacket, by the way. I think I can make it work and now I am on the hunt for buttons to replace the gold. If anyone has a good source (Etsy?) please let me know!
