Bernard Bernoulli is one of the main characters of Maniac Mansion 2 – Day of the Tentacle the classic game by LucasArts, which has most recently been remastered by Double Fine. Bernard has the look of a typical nerd but pair up with some of the other characters from the game and you’ll have a great group costume.

Starting from the top you can style your hair like a nerd or if you prefer you can pick up a nerdy looking wig.
Next, you’ll need a pair of nerdy glasses.

So for the pants you have some options. Personally, I would just grab any pair I already have that’s a dark gray/charcoal color. I would simply roll/fold the legs up underneath and then pin them so it looks like you have high water pants. Alternatively, you could pick up a pair of pants but get an inseam size that’s too short for you. So if you have a 32 inseam, you could try a pair of 30 inseam pants. Sounds like it could work. Third option would to actually hem up a pair of pants.If you did it by hand you could probably undo the hem after your done with the costume.
