This suggestion is two-fold:

1. Firstly, enabling shirts should be done while creating the event, not after already publishing the event, to streamline the event creation process.

2. Secondly, shirt sizes should be sent to the event creator from the YC platform, ideally via email, 2-3 weeks before the event. Some of our volunteer ambassadors who create volunteer events do no realize that they need to share forward their shirt size and quantity needs to us.
