I Am Gia Neptune Halo Pants

I am gia Neptune halo pants. Size XS. Hot pink and reflective. I love these but time to let them go! SOLD OUT. One flaw is with the belt that is attached, I can’t seem to get it unbuckled but it’s never bothered me I can still get the pants on and off with the belt buckled in I just can’t take the belt completely off. I’m sure it’s fixable I just don’t know how.
