I don't know much about fake fingernails (I
mentioned before, I've only ever worn them once, for a single night's Halloween party), but, assuming her everyday personal hygiene is as much of a wreck as everything else about her life, I wouldn't be surprised to learn she's using those tacky fakes to hide the fact that her real fingernails have a fungal infection. Because before I bought those cheap Chinese off-brand Halloween fakes I looked at a LOT of different options, in regular stores and beauty supply stores, and they had nails available in all price ranges and all kinds of different colors, lengths, widths, patterns and shapes--but I never saw ANY fakes as thick as the ones Tess wears. The only times I have ever seen such thick fingernails is in photographs of human fingernails or toenails with an advanced fungal infection.
Are there any recent photos of her with her natural fingernails visible, or even photos of her with fake nails of normal thickness?
