It's funny, if you asked me, I'd say, "yes, Century 21 had some very good value," but to be honest, I didn't really like shopping there and I'm not entirely sure why. I have no issue with bargain stores - I spent many happy hours picking through racks and bins or clothes in dusty old Filene's Basement (the original one in Boston) - but I rarely went to Century 21.
At 56 and as our culture has evolved to casual dress, I simply need fewer nice items of clothing. I have more dress clothes than I'll ever wear out as I was well stocked for daily suit-tie wearing and, then, in 2012 I switched to WFH. So between that and the fact that rarely is any event or evening out or anything a dress event anymore, I just don't need to buy almost any dress clothes anymore.
As to casual clothes - chinos, OCBDs, wool sweaters, non-dress shoes, etc. - I, too, am well stocked, but also find that I can "stalk" items on the internet and usually buy them at a great price from the original store on this or that sale (i.e., not Ebay or some other reseller), so why make the effort to go to a bargain store, which only works if you go regularly anyway.
Lastly, I want to own less items anyway as, like most of us, I wear 10%-20% of my clothes 80%-90% of the time and the rest sit idle. Hence, I'm trying to only buy items that will be actively worn, which, if you stick to that discipline, really reduces your purchases.
