I will never understand SF's current fascination with brown city suits. I can get on board with brown flannel or tweed (both preferably with some sort of pattern) for Winter or lighter brown linen or linen blend for Summer. But a fresco or other city suiting in brown, no.
I am a customer of Self Edge and SE is one of my favorite stores so I am not looking for an internet fight, but I share MrPorterBot's observation. I have been watching a few items that are well stocked and noticed a first further markdown yesterday.
I recommend you look at the Engineered Garments line. Their trousers sit at the natural waist. Also look at the Engineered Garments Workaday line. At a much higher price point, Loro Piana and Cucinelli will have what you are looking for.
