I ordered some draped tees, linen pants, and long linen skirts from them in 2014. Still get their catalogs, but haven't ordered anything since then (a bit of personal style shift).
The fabrics are really nice and substantial, especially the linen pants. I've found linen from other brands to sometimes be too sheer. Poetry's was hefty and draped nicely. Though check the item description first - I do think they use different weights of linen in different items. Summer items are probably of lighter weight, just guessing.
Also, they are generously sized, and go up to US18. Back in 2014, some skirts and pants gave you a choice of length. Don't know if they still do that.
When I bought the items, I was 5'10" and about 190lbs, curvey figure. Even the 14's were generous. Again, 3 years ago, so check their size charts first!
I like their colors, and how everything goes together. A bit like Eileen Fisher. The only con is that the sweaters look too boxy for where I'm trying to go with my closet - just me!
I'm really thinking about the velvet pants!!
I've never tried their shoes.
