All day But i wore it for 2/2,5 straight hours, then took it off for 30 minutes and then back on It takes about 10 minutes to bolt the wings back in place so taking them off needs a good reason (toilet break, sitting down break).
Yeah, that is virtually impossible with heavy wings. Some girls hide the wing ends in their corsets (2 fabric tubes at the back of a corset) so it looks like they sprout out of their back. But that's only possible with light weight wings.
The harness the way it is now is the only comfortable way. Wearing it like a backpack would create too much tension on my shoulders
