Hipster jeans with large wodge of fat (white and gently marbled with stretchmarks) heaving over the top. Thong giving the "arse sandwich" effect optional.
Fat women in vest tops (cover your arms! have you no shame?!).
The "Four Tits Effect" from wearing a bra that is too small. Ditto "Back Tits".
A very short skirt on unlovely legs, whether thin like chicken's legs with the knees being the widest part or porky and dimpled.
A very low top on someone with no tits, showing not cleavage, but an expanse of skin and bones.
Long greying hair. If you think you're young enough for long straight and stringy hair, then for God's sake, dye it. But better still, cut it.
The compulsory beige garments in polyester for everyone over fifty - trousers with sewn in crease which don't crease, beige "windcheater" jacket, beige acrylic "knit top". And the hair dyed a winning shade of beige to match. If I'm into beige when I'm 50, shoot me someone please.
