MrPorter customer service representative does now when exact date of sale until it's open to public. The call center and warehouse are 2 different locations. They majority communicate between emails. I believe the reason they think of that is net-a-porter. They are owned by same company and also has the same date of sale. The past summer's sale of both sites starts and end almost in the same date. Last year net-a-porter sales starts on Dec 1. I remember the date.
