Gear from Stormblood onward that covers the entire head tends to fully hide the ears of miqo'te.
In the past, this wasn't the case most of the time, as headpieces would often have holes for the ears to stick out or ear socks for them to stick in that sprouted out of the specific piece.
Headpieces such as the Calfskin Rider's Cap or the Street Cap, for example, are perfect candidates to get holes so that the ears can stick out but right now they entirely hide the ears of miqo'te instead, thus making it the only race that loses part of their racial features with this. Of course, viera and hrothgar can't even use them but would probably have similar issues if they could.
This is not a problem exclusive to miqo'te, viera or hrothgar however as some headpieces will also hide elezen and lalafell ears due to their size.
With the graphical update coming and eventually affecting all gear pieces, I would ask the developer team to please revise all the head pieces that could be suitable for the addition of ear holes and socks for the aforementioned races and especially miqo'te, viera and hrothgar.
If some people prefer getting their ears hidden in these cases, they could always add a toggle option to satisfy everyone, as it seems that the gear is initially designed for hyur, a race without these traits, and then adapted to the rest.
However, this trend of hiding the ears should not continue, as it limits the options for these races by removing their racial traits.
Another recent trend in EW has been to hide tails from specific pieces of armor (link), which I find problematic as well because of the further removal of racial features.

Are there headpieces that you would like to wear but don't because they hide the ears? Which examples of headgear would you like to have with ear socks or holes? Which ones would you like staying as they are?
