I know she's obviously not planning on skiing much but I'm curious if she even believes she could do "apres" in that outfit. It truly looks like she couldn't sit down in those bibs without bursting half the seams. Obviously she could be in a base layer for the other stuff, but you know she'll want to pose at a cafe in her expensive new gear to prove she's a skier.

Also, is it just me or is a 9-day ski trip that you're driving to*, and not even planning on skiing every day of, a bit excessive? I'm not a skier myself but I've done some outdoor activity trips that were 9-10 days and they're SO INTENSE. It seems like an obviously sedentary out of shape couple planning a 9-day ski trip is just them trying to avoid being around family at Christmas. Actually now that I'm typing that, I bet that's why she's going on about being "not the norm." She wants to believe they have this adventurous unconventional relationship rather than admitting to herself that she's not close with her family and also has no close friends. Hence running away to get married on a cruise, running away to go skiing for Christmas....
*ETA, by "driving" I meant I would understand someone from the US not just making a weekend trip to the alps in Europe, but for them it's obviously something they could just do a couple long weekends of throughout the ski season. You know they'd keel over if they tried being active 9 days in a row! It's a long drive but what's the point of just sitting around in an expensive tourist area for all those extra days?
