I've gotten sick of tights and leggings.  However, done right and with a great color, colored tights offer a lovely new touvh to any look.  Blue is my favorite color, and those electric blue tights on the femme on the left in Post #502 look very nice (though I'd avoid the gladiator sandals).  I'm kind of surprised she wasn't wearing red tights to go with those red accessories she's wearing.  *  The one in the center (same picture) has a tights-shoes combination that would be pretty comfortable with me.  Wearing black tights with black shoes are as classic a combination as anything.  The dark colors on her are offset by the beige skirt she's wearing.  What I did next was copy the picture and add a little gamma correction.  I was going to say that the center lady in Post #502 were wearing some cute high-heel loafers.  The shoes she's wearing are shoes that combine open-toe pumps with an oxford.  That's a great way to hide wearing ugly shoes.  I would have worn some cute loafers or maybe a pair of chic ankle boots.  I've never understood wearing a garment of a completely different color that doesn't match anything else being worn.  Kind of like seeing some femme in a green top, blue jeans, and hot pink Crocs clogs (or a knockoff).  
The picture below it... tacky tights.  Wearing metallic sandals only makes things worse along with those lavender high-waist shorts.  I'd never wear tights, so the guy in tights is beyond me.  On a lighter note, the last image in Post #502 is very okay mixing that dress with lemon yellow tights.  I like the dress as well as those tights.  Pairing them with a pair of mary janes are absolutely classic.  It's little girl cute on an adult body.  VERY classic and lovely to me.  Very playful and fun look.
