Also it's very important to accessorize your suit properly too.
I wear one of 2 Christian Louboutin limited city shoes in brown and of course red soles (I also have 2 Louboutin sneakers for more casual wear). Hermes apple watch band that matches the colour of one of Louboutin shoes. I have a Christian Louboutin street briefcase with a messenger bag in black and red. Some nice Paul Smith colourful socks. I have a couple different brands for ties, from Hermes to Stefano Ricco to Ermenegildo Zegna. Oh and you gotta smell fresh in a great suit so I'll wear Creed Aventus.
I don't do cufflinks or tie clips.
Tom Ford is a bit too expensive for most people I think, a few weeks ago I spend 400 Euro on a simple bracelet from them, but I agree they have amazing suits. . For people that watch the tv serie "Suits", Harvey generally wears suits from Tom Ford from what I remember (

I personally don't like to wear a full suit, I prefer to go around without jacket and tie. It fits better with who I am and in Italy it is to damn hot in the summer.
For jewelry (rings, bracelets, necklaces, etc.) I like to go with Alexander McQueen, Gucci, Tom Ford, Givenchy, Giovanni Raspini etc. And it's not even that expensive.
For bags, if I had the money I would go for Bottega Veneta. Else Burberry has also some beautiful bags.
In the end I prefer to go in sweatpants to work, it's just so damn comfy. Unfortunately it is not really acceptable where I go.
