Weather permitting a vest and tie alone can be snappy looking.
This is an easy way to set yourself apart yet still look dressy enough.
Vest should fit closely, adjuster on back should be needed for small tweaks only. Vest should be long enough to cover belt and bottom of tie with bottom button undone. Vest should not be obviously from a dressy three piece suit.
There’s good alternatives to chinos these days. I often wear cotton trousers in interesting, but not too interesting colors (dark reds, blues, greens). They can be cut as slacks or jeans. Wear a slim fit to get tapering from at least the knee down for a clean, height increasing look. Hem should come to top of shoe. Trouser leg break is for dads.
Shoes can also be casual by virtue of color (light brown should be perfect, grey if the rest of your outfit is in cool colors). Balance this with a traditional style (I love wing tip Oxfords, Chelsea boots go with practically anything) of good quality and on point condition.
Especially if you go with exposed shirt sleeves they should be close fitting for a put together look.
TL;DR. Contrast relaxed fabrics and colors with more on point, trim and tidy fit.
