I really like the black jacket that's paired with the b/w tie in post seven. Some of the white jackets could work too, but only divorced from the rest the gear. I think that's the key with Etro. Something that looks hideous as full suit or matched with all of that paisley could be good for a Summer's night on the town if worn with some more subtle pieces. The flower prints and panatoons would be next to impossible, but those are probably mainly show pieces. At least I'd hope so!
But if you take the jacket in the fifth post, get some solid colored pants, remove the wig and get a decent shirt, it could be pretty fun. The same with the grey/white pinstriped suit. They don't work together and definitely not with the waistcoat or eye patch, but if you balanced them against a solid color they could be worn.
It's interesting to see a relative lack of their standard striped button down shirts. I wonder if even they are tiring of that look or if they're just saving those for the stores.
