I'm 60 and I shop everywhere. I think there are some retailers whose zeitgeist I like more than others: Target, Talbots, Eddie Bauer. I feel like my style is casual, preppy, collegiate, sporty. I do know that as a size 12, I'm sized out of a lot of higher end stores and designers. I like the idea of JJill, but their sizing doesn't work for me -- large is way too big but medium is often a skosh small. I have a few pieces from Gap, mostly tops, because I'm too fat for their jeans and their dresses are too short for me now. I found a lot of items I really liked at Kohl's this year, which is unusual because I really don't like many of their stylings but for some reason, I liked a lot of the Simply Vera/Vera Wang stuff this past spring. I look at Chico's but the only things I like are their shirts. I love the look of items from JCrew, Banana Republic, Brooks Bros., Ann Taylor, Loft, etc. but I'm not their size. We just got an H&M and I've not spent any time there; I do sometime like things in Forever 21, but it's mostly too way too young for me. As far as nicer stores, I do like our local Von Maur, which is a Nebraska/Iowa version of Nordstrom. I like to shop and look because I am interested in how the stores are styling/merchandising the outfits, which I use for inspiration. So I can see something at Forever 21, and figure out how to make the look work for me.

I am 60 and I shop BR, Ann Taylor, and AT Loft, Macy's and Nordstroms.
That said last night when I was out to dinner a woman had on the a georgeous long tunic with black legging under it. The hostess asked her why she bought it at and she said at Forever 21. I am going to try and get by there tomorrow to look at it.

I personally think you can find aporpiate items at most stores you just have to look.
Would I except the Forever 21 item to be high quality no but a fun piece yes!
