I can not find this outfit in CAS

Have you tried clicking the Snowy Escape pack in CAS so you see all of the options that came with it. Left side of the clothing options click arrow and packs then Snowy Escape. Should make it a bunch easier to find. 

Yes, I did.

I play The Sims since 22 years. I am pretty good finding stuff, but this time I do not get it, how can I have it.

That is weird, I can't find it either.

Where did you find the image and are you sure it isn't custom content?

Maybe complete the mountain expedition? I’ve not done that yet. Do you get more than just the ability to edit the lot at the top of the mountain?

Oh isn't some clothing and skies, snowboard in the machine near the bottom of the ski trail? I'm going to check that and full body items.

Found them in full body. They are both women's wear.

Oh perhaps the second isn't exactly the same, can't find the hat. Must be locked away as @simsplayer818 suggests ♥

Similar in separates but not the same and not the swatches you have.

@ReneHollyDesign1 well done! I can only find the hooded one. It's enough to strain a person's eyes lol. I only have this one on my successful mountain climbing Sim. It's not there for non climbing Sims.

Edit: I've looked in tops/bottoms for Masculine and Feminine but can't find the red and blue one. This Sim has the bracelet and wall plaque for the mountain climbing expedition but she hadn't completed the Extreme Sports Enthusiast Aspiration, so I've done that now plus maxed Snowboard skill and still didn't get that. I also got the blue outfit that is similar to the missing one.

The hooded one should be unisex the other one is a two piece thing.

@crinrict Great work my eyes must be too old. LOL
