While sorting through my Mother's sewing basket I found an old pattern from the 50s or 60s, Simplicity 2390, the Answer Dress. A sleeveless jumper with a v-neck back, it is depicted on the cover in four views, belted, unbelted and with or without a puffy sleeved blouse (pattern also included.)
What had me curious was the name - Answer Dress. I couldn't help but think that whoever wore it (and in my mind, she's in an office in 1963) was a secretary, floating around the office, steno pad in hand, ready to have a letter dictated at a moment's notice, but she had all the answers.
A little research places the pattern in 1957, a chemise with a bateau neckline and a v-neck back. My sisters were a ways off from office work at that time and I was relieved to be rid of that vision of them in white gloves at their respective workplaces. Really it isn't a bad dress, a little sexy (maybe that's the answer,) easily dressed up and it's not hard to imagine it worn for a night out as well.
So maybe this was my Mother's dress after all. I'll have to ask her. She's in between the mild and moderate stages of Alzheimer's now with a memory much more in the past than present so she may have a good story to share.
