The conversation you had with someone in chat, reminds me of how some players either feel too tired to give a full explanation of how they feel on their opinions so they resort to lazy jokes, and comebacks/passive aggression. [it's like they forget as a consumer, we have a reason to dictate what we want, within reasons which tbh, are not over stepped in many situations that get push back. Think what Many will on Gender/Race/Glamour/PVP/Shop/Etc.]

it always felt weird when it broke off oddly through the armor and gear.
I'd almost want them to make the clothing ride higher on the bottom, or lower to just bypass the tail area to give an easier hole, or just be under the tail.[while the whole added slot/hole cover in some ARR clothing is nice. you can see how it changes in some.., Images on the net, specially if the body isn't vanilla with how the tail works as well.]

So for Actual clothing, simply Riding higher or lower would be an improvement.
For Capes, a split/a wide gap around where the tail should pass/or Simply put Variable Fabric Capes<Solid near the top, and going transparent nearer to the bottom, with a split near the tailzone/transparent could add a new style to it visually>. [For the huge gap near the tail, it would make physical sense that the cape could move in the wind whilst not being explicitly clipping through the tail. and the gap can be shapped in ways that fit the design, or detail of the Glamour/armor]

Toggles are a thing some have mentioned in threads and asked for. as some games have toggles for hoods<looks at WHM with hood in recent ad>, or opening/closing Cloaks/Jackets/Trenchcoats/etc. in the front.<makes sense I'd the outfit has clearly designed Clothes underneath> might even make it so certain effects of Glow of certain gear could disappear/turn off. Thus the who Cape Delete/Edit could work if they implement.

TLDR: with the unknown changes coming in 7.0 Graphics. we cant really through out past changes as set In stone.
SPECIALLY IF THEY PLAN 10 MORE YEARS.
