Brooklyn 19,
If the gemara says its deoreisa (as it does by showing ervah) it is deoraisa if it says somthing is derobonon then it is derobonon.
As for articles of clothing I beleive a couple may be mentioned however they are no longer worn (as style has changed considerably since then!)
However most articles of clothing depend on what is considerd normal in the society you are in (if somthing is considerd trashy or loud by the society you live in you shouldnt wear it if it is not you can wear it- as long as it is not revealing an ervah)
and this was my entire point.
as to what you were saying about listening to gedolim i discussed this in my post on page 6 of this thread.
