Hey Groupthink! I’ve spent countless hours trying to pick a simple duvet cover, but cannot seem to actually pull the trigger.

Does anyone have recommendations for a reasonably priced duvet cover (less that $2o0) that would be appropriate for spring/summer, and is soft? I am overwhelmed! Do I go with washed linen or cotton? Is expensive always better? Why do the reviews on Brooklinen vary so wildly? Halp!
