Tacky
Vulgar, of bad taste, loud, flashy, stupid and ugly. Bogans and female chavs often display outrageous tackiness without an ounce of shame. A vestimentary choice that says "I'm an ignorant, tasteless idiot and I'm pretty proud of it, thank you very much". A way to show your economic and intellectual poverty by dressing up in a way that immediately grabs attention, but also stabs you in both the retinas. A tacky person not only obviously lacks taste (and doesn't give a fù*$) but also really, really stands out in a crowd, and not in a good way. Someone who is very bad at basic fashion and has a totally delusional innate sense of self worth.
