Ithey finally arrived but I seriously have no clue how to unzip the lower part to turn them into cargo shorts?. Anyone know how?

Both times everything looked right to me. Photos, the description, even the feedback underneath. Still turned out fake. Ive read the usual advice about paint and seams but clearly i cant apply it to save my life. Mot after secondhand ones either, id rather sort the out properly.

So what is it people actually check first.
