Ok. HUGE different between the two colors. I accidentally bought both. The light blue are much smaller and do not fit true to size. These, the gray fit perfectly. I followed the size chart and have a pair the fit just the way I like now. I couldve sized down one too, but Im tall. Im 510 165# and wear an 8/10. The highwasir comes passed my belly button which is exactly what I was looking for.
