Graphic designer / communication-advisor seeking inspiration to upgrade my style!

Hey guys, I work in the branding business in Denmark, as a graphic designer / web designer / communication-advisor: creating full graphical identity's, webdesign, print design - bigger campaigns - content marketing and most thing in that field.

I know this is a wird question from a guy like me because it's my work to figure out how to build graphical brands, and I'm really good at this, so everyone would expect of me that I got my **** together, and I really do what I can in every corner of design; However I find that when it comes to me personally I have a allot harder time being subjective, and jump onto something than I have when working for clients ... besides that, though I have a good overall design / aesthetic sense, I'm not at all an expert in fashion.

Most ppl in my business go totally wild: tight leather pants and partisan scarfs, you know what I mean ... that was me 5 years ago perhaps, where I always whore military pants, and white shirts, with the same black converse I still love today...

I also gotten about 20 kg fatter lol, and older, and now work with a lot less creative customers(think classic businessmen), so that changes the game... I'm 34 years old.

At the moment I always rock black/grey/marine-blue chinos - at winter I most often have a grey/marineblue/grey v-neck sweather pulled over a white shirt; outside I wear a marine blue pea-coat, wine read scarf, black leather gloves, - suede blue lloyd boots.

At sommer I usually where the same pants, dress all the way down to a simple black t-shirt, simple white shirt, perhaps a blazer over sometimes - untill now I have rocked black leather converse hi's, and when it's really warm bare-feet boat shoes, but is considering switching over to real shoes this fall..

I basically look rather booring, stable, caual guy ... which suit me fine ... my clients is very diverse, everything from high end business men, to someone exepecting more of a creative revelation ...

The office I work at, is a creative office, mostly with wild movie persons, think creative young ppl, in jeans and partisan scarfs and so on... most of them cool hipster types, which works for them and their customers... I don't want to go totally for that stereo type though ...

What I'm looking for here, is just as many sources of inspiration as posible (and yes I'm already, always browsing, but since you guys is the **** at this, perhaps some of you have fallen over some awesome ideas, I would never even think off myself).

How can I take the style I have now to a higher level? how can I tweak it, change it?

Should I go back to the army pants look? lool...

What can I do to brand myself better tough my look? that is how do I stand out more in terms of look, how can I get to look more like what I do?! Without becoming less serious in the eyes of my more stylish/corporate customers (or merely customers like restaurants, hotels and so on, I have many of such customers).

Thnx

Uh, that's plenty of information but no pictures and few obvious limiting factors.

Upgrade the footwear.
[lose weight, please, before the next steps]
Buy some patterned shirts, such as gray gingham.
Buy some interesting, quality belts.
Wear quality jeans sometimes (but not with conservative customers).
