Bring back functional drawstrings

So I’m looking for some sweatpants and I don’t know why they all have that scrunch elastic on the waist like it’s so annoying cause why could just put a drawstring on there so I can tighten the pants as much as I want and loosen when I want. And idk is it’s just me but I don’t exactly wear sweatpants so snatch my waist so I don’t see why the scrunch needs to be there (I’ve don’t absolutely 0 research on this to be fair) and another thing is that as a mid/plus sized gal I hate how it squeezes me even when I get my size. Anywho goodnight
