Hmmm. I think two when I hear pigtails. I can't "hear" it, mentally, without the "s."
When I had long hair, and wore, er, double ponies? (that sounds even dirtier) I was (a) well aware that a schoolgirl connotation might be construed (b) sometimes going a little for the naughty schoolgirl thing and (c) sometimes I kinda had dirty hair and it kept hair out of my face.
And hi, skewed logic, even though you're 18 and I'll cut you a little slack. Should teenage girls not be wearing their hair in "girlish" styles, because it makes some people think they're -- GASP-- schoolgirls? Um.
Honey, welcome to the grown-up world. ANYTHING can be seen as sexy.
And sometimes pigtails are just pigtails.
Note to self: do not google pigtails with SafeSearch off. Even with SafeSearch on "moderate," almost half the results are porn.
Oh, and in my househld, growing up, two pony tails high on the head on the sides were called "Buffies" or "Buffy-tails", from Buffy in Family Affair(??) This is hw I wore my hair most often in 1st grade.
I'm old as dirt and wear pigtails.
The girl who's had short hair her whole life has no opinion, unsurprisingly.
I still think (unsurprisingly) that I am right, because pigs' tails are short and ponies' tails are long. See, very logical!
I tend to use Steph's definition too.
I also will 'fess up to wearing my hair in pigtails on occasion. Oh. Well.
One=pony
Two or more=pig
braided hair=braid
I wore pigtails when I felt like it up until my late 30s. Looked good, too.
That's one thing I miss about longer hair, pigtails. I remember seeing the Buffy ep when she wore them doubled up, with the ends sticking out, and I was all "OMG GENIUS SUMMER HAIR" and it immediately became my go-to exercise hair.
My hair is too short now for pigtails, but I wore them and still would when inspired. When I ran and wore a hat, I loved pigtails, low, because I could still wear a hat (like Jilli said, but a baseball cap).
Grace wears her hair in pigtails almost every day, but I guess that doesn't count.
