Carrier??

So I have the Lille baby all seasons carrier and no matter what I do the straps are too long for the bottom to sit comfortably around my pelvis where it is supposed to be. I have cris crossed them and tightened them as far as they will go with no avail. But I’m 5’ 7” so I’m not sure what the issue is? Can anyone else recommend a Carrier that does all of the positions the Lille does but have tighter straps??
