They may have given me free delivery too, but I can't remember. I don't really pay attention to free delivery offers as I always choose next-day delivery.
I am a superstar.
For shirts and pants I prefer mono-product producing Italian brands for their superior tailoring, quality and competitive pricing. Business casual pants I've bought and liked: Rota, Giab's, Berwich, Siviglia. From other total look brands with more availability and lower price on Yoox and are also good: Aspesi, L.B.M (Luigi Bianchi Mantova/(Rough), Brando, Lubiam), Daniele Alessandrini.
Shirts I'll just mention the brands I buy and currently highly available on Yoox: Aglini, Glanshirt, Borriello, Mazzarelli, Ingram. I find their fit on the trimmer side. I also like Barena and Massimo Alba's shirts that are slightly looser fitting.
