@Oaktavia i think your 555-01's look great. i bought my usual tag size (31) and they were comfy (not to tight, not to loose) out of the bag. I think there's just something very special about this flag ship 21oz denim.. I feel like you could were it super tight and let it loosen over time or you could wear it loose and easy. I think you're right in that sweet spot.
Here's a couple fit pics from shortly after i bought mine from Berkeley Supply Co. in Denver (Great dudes BTW)
