That's incredibly gorgeous Illudia Absurdus, especially the third outfit. It does look like a 17th century sailor outfit, especially from the back; she wouldnt look out of place on a crow's nest, or swabbing the decks while singing a bawdy sailor song. Kudos
As for the boots for the first outfit, perhaps the 1k Istani? They have a fairly plain design. There is one small part of the boot that can't be dyed though (I believe the base colour is brown).
