The desire to make one is tempting especially as currently on my 'sewing to-do list is an orange jacket. It certainly is tempting to making matching trousers so the option to wear it as one is there!
Balenciaga And Lanvin we just two of the many designers who sent suits down the runway, usually all in one colour from the lurid and loud right through to the more conservative colours of blacks and neutrals. and if your not a fan of wearing a head to to suit that why not try a shorts version, which was equally as popular and quite possibly a little more chic!

Sewing your own Style:
thinking of making your own suit? There's a fair amount of choice. My pick would be Colette's clover trouser pattern paired with by hand londons, Victoria blazer, although sewaholic's cordova jacket is tempting to spice things up.
For longevity and a more classic approach there's the Vogue patterns which should be just as relevant in 20 years or so as it is now, although maybe not in lime green!
You could even cheat. If you've already made a suit style jacket, or trousers why not a make the co-coordinating separate to match! and as for an undergarment to the jacket, you could keep it really runway and wear nothing but a bra, or keep it simple and pair with a white vest top or fitted t-shirt. If you really wanted to up your game then making a pair of matching shorts would certainly do the trick!.
