This week and last week on GH, Lulu has been conspiring to hide Johnny, and her plan to get rid of Valerie went too far. During these scenes, Lulu was wearing a blue chambray button down shirt with a single chest pocket from J. Crew. Lulu's "Always Chambray Shirt" comes in regular, petite, and tall sizing. I confirmed that the shirt is an exact match by comparing the stitching, back seams, faded banding pattern on the arms, buttons, etc.

Here's a comparison of the back seams.
