r.e. Trousers - why not get them made up? Then you can specify exactly how you want them cut, fabric, etc.. As well as a couple of bespoke suits, I have had some lovely trousers made up at Matthew Lawrence's place in Paddington. Think I paid around $180 a pair. Also try a decent tailors. I have a suit in for alterations at M&R Tailors on York St at the moment and he seemed very knowledgeable (but I haven't got my suit back so can't vouch for them yet). You will want to start a relationship with a good tailors, so getting a pair of trousers made up is a decent way to start. Loake 1880's - They run a little large for me too. Can't comment on Meermins.
