Arc'teryx Volta Jacket - Women's

I already have an Arc'teryx softshell and an old ski jacket. However, being down with Bronchitis I decided to get an insulated jacket and stumbled across the Volta. I wouldn't have flinched at a $600-700 tag but $1,000 did make me think twice, especially when I asked the salesperson what the difference was between the Moray and the Volta (same Proshell, same insulation) and she said very little, apart from the more fitted cut and the colors (and the $300 price difference). Vanity got the better of me and I decided to make an "investment in my health" (or so the excuse was) and bought the Volta. I'm a 35-25-36 and wanted an XS for a snug fit but couldn't find any for the color I wanted. Got the S instead. Their measurements give 2" or so. Their measurements for the S specify 35 for the bust but I can fit in 4 layers + fleece in the S.

Took it out the last few days, 9 degrees at the base. Before the purchase, I had my old ski jacket on (not insulated) and 4 layers + fleece. Yes I know that's a lot of layers for many of you but I didn't want to risk if with Bronchitis and all. After the purchase, I had 4 layers + Volta, and I didn't find myself any warmer at the top of the tram ride, which was kindda disappointing. Basically the Volta = my old ski jacket + fleece. In hindsight, would I have gone ahead with the Volta? Well, with a wedding coming up and an evening gown (coincidentally also $1,000) I've had an eye on, probably not, I would have gotten the evening gown rather than the Volta.
