Thanks to everyone who replied!
First, the purple was indeed the one I thought might have a chance! The brown ones are looking a little blah to me, verging on cutesy with the little bows, and the black ones just seem totally off.
This probably isn't a look I'd wear a huge amount, but seeing so many canvas sneakers on sale and posted here had kind of got me thinking about a pair because they seem so fun, and it would be nice to have one pair of cute summery casual shoes that are a little sturdier than sandals or delicate flats. Since I already had these all in my closet, I thought I may as well pull them out and see if any of them might satisfy the urge. (And "unearthed" was probably the wrong word, since I've been wearing these all once in a while when I want to shove my feet into something really easy to go outside with a book or run to CVS, but just haven't been looking at them with any kind of critical eye.)
I think I'll keep the purple for now and see if I reach for them, and toss the other two. Maybe think about a new pair that's a little more current, and also more of a neutral. If I did get a new pair, I think it would be something like this or this. Or maybe this without the bow in the back. I feel like the types Dashielle mentioned might make me look stumpy or overwhelm my foot and aren't speaking to me as much, even though they're probably the trendiest versions. But maybe something along the lines of the versions I linked to would be a good balance?
