Hey OP, nice choices!
I like the blue suit you chose. If you want to save some money, you can skip the vest and go 2 piece. There may be occasions to wear the vest, but usually you will probably keep it at home. That said, it could work well on you as a professor to skip the jacket and wear the vest.
I also like the charcoal suit. Definitely go 2 piece on this though.
I would suggest you consider swapping out the black suit for a lighter grey suit. Check out the essential grey, or the essential grey herringbone. I have a black suit and a light grey suit and I wear my light grey one 10x more.
For shirts, I have the lavender and the light blue you have chosen. The lavender is actually a bit more intense then it appears in the picture. I wear it with my blue suit, but that's it. I would suggest swapping it out for a white shirt. It'll go with everything.
For the future, you can think of getting some patterned shirts. Generally, the rule of thumb for patterns and solids is suit:shirt:tie = pattern:solid

attern or solid

attern:solid. Of course solid:solid:solid works well too. I've got the light blue gingham from indochino and it is one of my most worn shirts.
Also, use "SHIRTBUNDLES" when ordering and you'll get 3 standard shirts for $240.
Oh, and take the time to get measured properly.
FYI: when ordering a big batch like this for your first time, indochino will usually make one suit and maybe one shirt first. They'll send them to you to test the fit, and then once you finalize the fit and measurements, they'll make and send everything else.
