I think it's pretty obvious they're too small...especially in the middle pic...looks like leggings to me. I would size up if I was you!

Mine looked similar... and they never felt quite right (even after a month of hard wear). Even going to 32 didn't do it for me. I'm doing 33 PNS now. So the answer? Yes, size up.
So I've been searching around for a pair of light blue Seinfeld-esque jeans without copious amounts of wash effects, and I think these are it.
The only questions that remain are: is this Petit New Standard Light Blue Denim raw denim, or just regular, don't-size-down-2-sizes, don't-worry-about-APC-tier-waist-stretching denim? Ultimately, I'm just wondering if I should size down or not (I typically wear a 28 in 3sixteens which are now a perfect, slightly loose fit around my waist after ~6 months), because this pair doesn't look like raw denim.
