For club tournaments that need it, who sometimes uses a waistcoat and where did you get it?

I have been looking at sportsdirect and amazon for a descent one for a cheap price but it would need 2 real pockets to put the chalk in.
Like, unfortunantly it doesn't always mention if the pockets are real or decorative.

If i'd order from sportsdirect i'd like one of those Rocket towels too..


Went to a local sportsdirect shop yesterday but they didn't have any waistcoats, or that towel.
