You're never too old for GG! Maybe I look silly but I don't care! I'm 61 and have the silver leather midrise and a dirty white Superstar with some gold and silver sequins. I found they run small and narrow. I wear a 10 and had to get 41 and still have to unlace them way down to get them on and use footies instead of socks to fit into them. JME.
I’m 100% certain you look awesome and NOT silly in them! I love wearing something so special that not a lot of people now what that are when I’m wearing them! Makes them extra special IMO!
