^ no offence, but I find that one lacks imagination if he matches his pocket square (PS) to the colour of his shirt &/or tie. As it's been discussed a few times on this forum, a PS is an extra element that adds colour or brightens up an ensemble. So wearing a PS that is of the same colour as your shirt (of course there're exceptions) is, as I find, pointless.
As for buying or choosing a pocket square, there isn't any particular method used. Just buy whatever catches your eye. Edited by Fantastic Mr Foxx - 8/15/11 at 9:34pm
