When I began training I was at a small uncontrolled field in a small town. No one was ever dressed up especially nice and during my training I never felt out of place in jeans or a t-shirt. Now that I'm working on IFR I've switched to a school located at KBED, a reliever airport for KBOS. Where I am on the field it's very nice and seems to promote a business class feel. I've gone for a few lessons and always feel under dressed. Some instructors wear nice shoes, slacks, and button fronts with ties (the classic pilots white with black ties, some even with epaulets)and some just nice polos and dress sweaters. I know I need to dress better at least when I go there, but don't want too look ridiculous. My question is three fold.
Would wearing a sweater like below with slacks and a white button front look pompous for a student at a nice airport like KBED?

Is a suit too formal? If so, is a sports coat, button front, and slacks better if there is multiple colors?
And finally, what would you just recommend?
Please don't rip me a new one guys and gals, I'm asking here to avoid embarrassment because I sincerely don't know. Thanks in advance!
