Suit shops?

Hi fellow Yorkies, any recommendations on where to get a suit from? Got a few weddings this year from April through to September, and all with the same people.

Trouble is that the main retailers now are all some sort of fabric blend that makes these suits feel plasticy in texture. My preference would be for 100% wool (or close to) as this feels softer.

Also, to add, I need short length for jackets and many places in the outlet do regular length only. Or if they come as a set, the regular length jackets usually mean 32 waist trousers when I'm a 30. I don't see the point in paying for something good then having to fork out more for alterations that will work out at £100-200 by the time the jacket length, sleeves and shoulders are adjusted as well as the trousers for both length +/- waist.

Main thing with a suit is differeny styles have different fits. I don't want to get caught in this trap of buying online only to find a comical frequency to the post office for returns when things don't fit. Which means somewhere to try things on with a decent range.

Thanks in advance for the suggestions
