The costumes in here are very nice! 1920's era dresses are featured and some of the headdresses that are worn are very pretty.
You might also recognize a few of the actresses as you watch through the series. Bea is played by Stella Gonet, who you might recognize as Mrs. Musgrove from Persuasion (2007). Louise Lombard, who plays Evie, is in the TV series CSI. In a couple of episodes, Elizabeth Garvie, who was in the 1980s version of Pride and Prejudice, was Lady Elizabeth Montford. Phyllida Law was in an episode; you might recognize her from the Gwenyth Paltrow Emma and as the mother of Sophie Thompson (Miss Bates from the same Emma) and Emma Thompson (Elinor Dashwood from Sense and Sensibility).
It's a really interesting series. I might review it at some point. I haven't watched all of it yet (I'm almost at season 3), so it might be a while before I review it. There is some suggestive language and one scene in one episode that was a little mature, but the scene was very brief.
This series really holds your attention as you watch through the episodes. There are three seasons in total, which you can buy separately or in one collection.
