Ah, but this is where it comes to how you pick your wardrobe (and visiting London you’re in a good place to make it happen): start only buying suits which come with two pairs of trousers (bespoke/ made to measure is one way, you can also buy value suits in the UK with 2 trousers) and also invest in dress shoes which are reasonably comfortable - on a budget get some of their horrendous hybrid US-type things, or in the UK get yourself a pair of hand-grade Crocket and Jones which will last you years and be kind on your feet.
