Per photo, when I see some modern Mixtes and frames, that Schwinn doesn't look bad at all and I do like the color.
SCHWINN WOMEN'S MIFFLIN 28" HYBRID BIKE- GOLD Similar Schwinn, much more than the Mixte in post
#1 ; I'll have to try to get in to those stores soon myself.
I've looked at some modern Mixtes as someone mentioned one company above, of course, these Schwinns are not lugged in that sense but it looks somewhat light, not too bad to me.
Mixtes naturally seem to have a retro-look to them, the downtube on these though are fairly wide though, 28" tires. Interesting.
