Assuredly not. The point isn't to match every possible combination, but to learn to deal with the general restrictions and advantages of the clothing. That's why I want folks to wear something they'd commonly wear, that's not like a gi. If they wear sweats to a "street clothes" class, they aren't getting the benefit...unless that's what they normally wear (like my uncle).
And if everyone wears something they'd commonly wear, you end up working with partners in a vast array of clothing, so you get to see what advantages and disadvantages an attacker's clothing might present.
If you are distracted by your clothes in a fight. Being punched in the face is going to come as a real surprise.
