I don't know if there's a such thing as 'authentic' drow armor. The aesthetic varies from edition to edition, artist to artist. For what it's worth IMO what Larian has made is a bit unique in the styling, but falls broadly into the general aesthetic-and looks good too. Fingers crossed for some heavier armors though-drow used light chain armor a lot in the books and previous editions-I know chain shirts are pretty rubbish compared to 3rd edition, but some medium armor would be nice to see.
