petites are back there too - crammed in to a tiny little corner, I think "maternity" is the holy dividing ground between plus and petite sections so we dont accidently end up in the wrong section.
And god help you if you are petite AND plus sized. Because nothing helps a short fat woman look good like "cuffing" the 8 extra inches of material at the bottom of the pants.
If you are not "normal" then you gotta go to the back of the store. (who is normal by the way?)
