Well, I'm as fake as they come, and revel in it :-)
Hair: the real stuff is thin, short, of indeterminate color, and depressing...but it's ok because I never have to look at it. I always wear a very expensive hairpiece that turns me into a knockout blonde. For regular wear I have two long (20") 3/4 wigs (halfway between a fall and a full wig) that I alternate. I carefully (and firmly) apply them, and blend into my front hairs, which I color to exactly match the wig. You could almost look at me with a magnifying glass and have trouble spotting it. Because I wouldn't be caught dead with what's underneath, I actually have several others for special occasions (an up-do, one for swimming, etc.) which are all the same shade.
Eyelashes: false, of course. I used to go overboard and wear the kind of ridiculous caterpillars that Liza Minelli does, but these days the lashes are long but very realistic.
Makeup: my skin is ok (no acne or anything), but it's pretty sallow, so I wear quite a bit of makeup (foundation, contouring cream, three shades of eyeshadow, eyebrow pencil, two shades of blush, two shades of lipstick and lip liner, two coats of lip gloss and powder for the full evening effect, a bit less during the day), which changes depending on the lights under which I'll be seen. I take a lot of pride in my artistry, although it takes time.
Teeth: I got implants, so I have a Hollywood-type smile.
Breasts: What do you expect?! I'm a natural AA cup, but have always felt that nature meant for me to be a bombshell...so I need to give her a little help. That said, I'm not into permanent surgery (I can't even THINK about it without cringing), so my top consists of C-cup falsies in special Curves bras that have neat pockets for them. These aren't the foam sponges of my youth; I'm talking about high-grade silicone boys here, which look, bounce, and (when the occasion warrants) feel like the real deal.
Stomach: a relatively heavy-duty shaper, which gives the same effect as if I went around sucking in my tummy...but with a lot less effort (it does get a bit constricting at times, but it sure looks good.)
Nails: acrylic, carefully maintained, changed every week, with two shades of nail polish.
Tush: even though I'm getting a little porky in the middle, I'm afraid I'm flat as a board down below, so I got myself a nifty pair of padded panties. I don't wear them all the time, but when it's time to put on something appropriately form-fitting, I slip in my not-so-little friends, and I instantly become a wolf-whistle magnet. (Seriously, even more than the boobs, a big bottom sends off sexy signals like you wouldn't believe.)
Shoes: I'm not a shrimp, but the 4" heels make my legs look sleeker and nudge me close to super-model territory.
So, what happens, you might ask, when the boys get a little frisky (I'm not married, and lead a pretty active social life)? It turns out that when handled appropriately (which is probably a whole topic in itself) not only do they generally not really mind, but some of them actually LIKE the artifice, and get their jollies by helping me 'dress'!
I guess this all makes me a bit of an outlier here, but I have no problem working hard to look my best, and when I feel good about myself it shows, and in turn ensures that others feel the same way.
