They didn't show the dress, but it might have been a dog for any age !
I think the simple answer is "yes" in the sense that it is harder to look good in ALGO when you are older. Not really sure why!
So words like simplicity, restraint, elegance are often used in an advisory way.
I don't take that to mean "no embellishment". It means select an area or feature you want to highlight and don't have a lot of other competing items. So if you have a jeweled collar you might forego any other bling elsewear.
Pattern--hmph. You can find websites that say, no patterns after 50! That seems daft, but if you look at actual OUTFITS you may be able to see, in this outfit the pattern is worn in not the best place, or size, or proportions or whatever. So, a patterned top worn over some dark bottoms may look kind of meh, whereas a tonal outfit would look sleeker. But the same patterned top styled another way,--I don't know, maybe something like the bookending concept or what accessories you use--looks fab. I think it may be that it is just harder to wear patterns in the most flattering ways because by definition, pattern introduces way more variables. It doesn't mean it takes some heroic effort, though.
Several forum members had some spot-on remarks on this topic when they said something like, , and I'm paraphrasing--it's not that younger women always look good in what they wear--it's that we are more tolerant of their developing judgement, whereas the older woman who looks tacky seems like she ought to have learned better, or could afford better.
I just loved that!
Everywhere you can see young people not dressing their body types just as much or worse than older women--it's maybe just less disastrous when they do that. They've got that youthful energy and glowing skin or whatever and that can elevate the total package, IMO. That young woman might still be 100x more fab if she dressed "better", though.
