Tips on Matching Patterns and Tucking In Shirts

Question from P:

Matching patterns on shirts with patterns on ties. Matching patterns in general

Problem with dressing sharp… hiding the midsection. One can only go so far. Using garters or shirt stays. Sure you look well tucked in but it accentuates the midsection. Any tips there?

Here’s a dumb question. Do I tuck in Polo shirts in jeans?

Can a polo shirt be worn with a necktie?

I personally find the combination of a polo shirt with a tie completely crazy and unfashionable. But I’ve seen it lately and out of curiosity, I’d like to hear your opinion on this topic. Can a conservative polo be worn with a fairly casually textured tie in any occasion???
