This is the issue with you people talking about something without doing any prior research. Apart from 3 of those all are older than 2010. FC has not worn Shalwaar Kameez since 2010s. The three newer than 2010, two are from at least 4 years ago, one being from an older PSL and one is from soldiers deployed on COVID duties to enforce lockdowns, why would they kneed elbow and knee pads there? It’s been 12 years since then, which is when most of the re-equipment happened. Go look at some recent photos kindly.
I will re-iterate: all soldiers, including FC, have knee and elbow pads as standard issue, and the rest of the stuff is standard issue when deployed. This standardization started in 2005 and then spread to all forces in 2013 and was completely done by 2019-20. Nobody wears Shalwaar Kameez either, even as a non-combat uniform. Except Punjab rangers during ceremonies.
these below are all regular soldiers. Including the pics from FC.
You can check the army and FC multimedia channels for newer pictures.
