Recently just purchased this Asos navy suit. ASOS Slim Fit Dark Navy Suit at ASOSheap and cheerful as I don't have the cash and all I'm wearing it for is three weddings, March/April/May of this year and then maybe the odd cheeky interview.
The only other time I've worn a suit is for proms etc so I'm not very confident in piecing and outfit together yet.

I was just wondering if there was any advice for the shirts and tie combinations that would go with this suit. Next have some nice green and red oxfords that come with ties. Is this a bit too lazy? I also fancy getting involved with a pocket square or would this be too much?

Any advice would be greatly appreciated!
