Stretching the Shop and Product Pages

Hello,

Is it possible to stretch the content of the shop page and individual product pages? If I create a new page i can do it with row widgets but how to do it on the pre-defined pages?
I am looking for something almost exactly like this:
https://www.versace.com/us/en-us/women/bags/shoulder-bags/
and
https://www.versace.com/us/en-us/women/bags/shoulder-bags/onyx-bouquet-print-quilted-medusa-evening-bag-dnmot/DBSG377-DNS2F_DNMOT.html?cgid=142200#start=1
Sticky Product also does not seem to be working for me.

Thank you,
