I am a fashion designer and working on my first upcoming collection after graduation. Therefore I want to do all the graphics properly and perfectly well - as best as possible, of course and now I think about buying a new MacBook in order to get the newest programs and the best working capacity.

Which one can you recommend me if you know, that I want to carry it with me every time I have a meeting or a presentation?

Just about any of the MacBook Pro models will do nicely. If carrying weight is a factor, stick to the 13 inch size (15 inch if you really think you need the screen size). In my opinion, the 17 inch model is simply too large for practical mobility. Some folks like the Air for its light weight and size.

The Air probably won't do for [heavier] graphics at all, not even the newer models. It simply isn't built for that kind of number-crunching.

MacBook 13" or any MacBookPro with proper amount of RAM (at least 4GB RAM to boot) and a good external display of at least 22", preferably 24" and upwards should get you a long way. Pro models also look more professional being made of aluminum. 13" MacBook/Pro is actually portable and able. And like the Bozo said, 13" may lack the screen size but 17" isn't really portable, it's draggable/luggable.

External display for actual work-work is advisable even because of the glossy screens on these laptops. Besides, you can get a serious monitor with the price difference between the 13" and 15" models so it may be something worth considering also.

Agreed.. laptop screen color is always off from what it should be... even with a calibrator.
