UK - cheaper options for shoes/suits?
For shoes everyone recommends church's/ cheaney's but I was hoping for black oxfords possibly under £100/£150. Would these be acceptable to wear? https://www.clarks.co.uk/c/Stanford-Walk/p/261478… , or if not please offer alternatives
For suits I don't currently own one, is it best to start off with a dark navy one? Is it okay to get a cheap one from debenhams/next (e.g. https://www.next.co.uk/g252201s3/834824#834824) or is it worth dropping £300 on a suitsupply one?
Additionally, if I'm wearing black shoes with a dark navy suit what tie colours can I wear?
Thanks for any advice
