The 'age appropriate' dress issue arises at both ends of the scale. Finding something casual for us 50 Somethings is nearly impossible. I guess we're suppose to either wear the stuff of teenie boppers or the stuff they wear at Sunshine Acres Retirement Village. There's nothing available for those of us inbetween.
Now that you mention it, it has been more difficult to find something to wear. I have to stick to boring classic, otherwise it's too too either way. Only occasionally do I happen across something fun and age appropriate.
Have you discovered the new jeans with Lycra? They are great. I like the kind that are made from a thinner denim. So comfy and they look great.
