I'm 5'2" and, like Mo, come from a family of fairly tall people. My mom used to be the shortest in our whole large extended family at 5'3" until I grew up (not! lol) and took away her grown and before her, my great-aunt held the "shortest" title, also at 5'3". The rest of the women are all 5'6" or taller and our guys are all over 6'.
Despite that, I've never really felt short. As I like to tell my teenage son, I'm tall for my size and what I lack in height I make up for in spirit!
I didn't learn about correct fit in clothing until about 3 or 4 years ago (when I started watching What Not to Wear!) so I don't think shopping bothered me that much since I didn't realize all my stuff was too long in the first place. I did start wearing heels so that my pants wouldn't drag the ground, but in the end, I just fell in love with them. Love how they look, love the sound of me walking across a room in them, and when I slip on a pair of heels it gives me "attitude." I feel sexy and confident in a pair of pretty heels so that's why I wear them. Since I don't really think of myself as short, I've never worn them to try to feel tall...and, in fact, I feel like my bottom is more of a hindrance to finding clothes than my height.
That said, I do have the "can't reach the top shelf" issues... And now that my oldest is in high school, I have to be more concerned about looking "age appropriate" because practically all the kids at his school seem to be taller than me... so it's easy to be mistaken as another teenager if I'm dressed down. That has pluses and minuses... I'm just a few years shy of 40, so I feel like it's a blessing that I'm aging well, even if I have to bear my son teasing me that his friend's think I'm his sister.
ETA: My whole real point is that maybe I'm obtuse but I didn't realize anyone was putting down short people here or elsewhere. Maybe it's the circles I hang in, but most of the people I know or have met online in terms of fashion, really stress making the best of yourself whatever you look like. It just occurred to me that maybe all the leg lengthening talk could be putting down short people but I just figured that was a cultural thing... Americans love long legged women and since every model we see is generally pretty tall, we're kinda brainwashed into that. But that's why I don't read fashion mags anymore and rather get my fashion tips and fix from YLF and what-i-wore today type blogs.
