As ive pointed out before: history, bareley covered warriors are pretty common with tribal societies and to me, this does not interfere with the believeability of the setting at all.
However i think that is not the same issue here: Elves look like elves do in this setting, the female elves dont look any less covered than the male elves, as such it is quite easy to deduce that it is simply how elves dress in this setting and how they go to battle.
could a reason why the elves (male & female) have such revealing armor and that its made out of leaves and wood (light,but durable material) aside that its how they dress, that they are a race who favors combat mobility, at least that is what i get out from their armor designs, that they are a swift moving race that favours mobility in all forms of combat, be it magic or normal fighting with swords.
