Tips for the bigger guy

Hi, basically I’m a big guy (I’m XXL) but I love dressing either smart casual or formally for all occasions work or play.

Are there any hints or tips in regards to different materials/patterns/clothing items in particular for a guy of my size? and any that would help make people not pay attention so much to my size, but more so to my style/clothing?

Thanks.

Do these brown shoes go with navy and grey suits?

I’m concerned the color of the soles is too flashy (non-conservative) to go with suits. I’m having a hard time picturing it in my head. I need some advice!
