its the waxes (in this cases bees wax) that cracking off making the effect of "dusting" (make creasing areas look lighter)! Nothing to worry about!! just brush and with time it ll go away! hope i helped a little bit
The shoes are cemented ( the welt here is just for decorating reason)! A good cobbler ll be able to resole them if needed quit easily ! In your case you just need to glue them back down!! Nothing major to consider about !!
Great jacket Justin Don i am not sure if it is the posture or pants need a little pull in at the leg area and the sleeves a little pull in too!! Other than that this is a really beautiful suit and the color combination is just exceptional!! (btw the color of the suit match perfectly with your tones)
