On a Miqo'te Female
When using Arachne Culottes of Healing and Storm Elite's Boots there is a gap between the leg and boot mesh on the outside of the thigh. This only seems to occur with this combination of pants and boots. Using other boots, or using other pants does not have the same problem, for example, the gap is not present using the same boots and the Valentione Skirt.
