Whats wrong with the elastic waist band and super extra large bagginess? Don't you know its the style...that is what they are hoping that you will turn into as a Chef...very wide and baggy! Its like wearing sweat pants to work all the time!
Kidding aside...They make them that way so they have a very universal fit, most chef clothes companies only make a few sizes, (small, medium, large, XXXXX-large)...this saves them money but also you are able to have one size that will fit most of your staff.
What makes them specifically chef clothes is the material, you ideally want something that will not catch on fire easily(cotton/wool/fire resistant poly-blends) and will be cool and comfortable for the long hours in a hot kitchen and on your feet all day...So you still want to be a Cook huh?
I can't speak for Bauman, but what I imagine is that they want you to have something that falls along industry standards and that you have some uniformity with the other students. So I imagine that if you find a pair of very comfortable cotton (not jean material), black pants, that you would be inline with their policies.
I've tried alot of different brands, but the one I keep coming back to is "Chefwear". They have the best fit, materials and craftsmanship. You'll pay a premium, but they will be your unique signature and will last you awhile. Just be sure to go with a darker color (even black), so it will be easy to cover the beet and curry stains!
