A hipster (35+) who takes a modern, but yet old expensive piece of clothing and pairs it with mostly inexpensive items purchased from Nordstrom's Rack or Marshall's. Basically, they put their own SPIN on their old expensive clothing and thus making it AWESOME = SPINSTER!
A new trendy hoodie with an old expensive leather skirt and v-Itaglia boots or paul green shoes (and sometimes awesome knee socks), hence, you are a SPINster!
A spinster, or old maid, is an older, childless woman who has never been married. A "spinster" is not simply a "single" woman, but a woman who has not formed a human pair bond by the time she is approaching or has reached menopause and the end of her reproductive lifespan
I fear Sarah-Jane is going to end up a lonely spinster with only a cat by her side for company.
