No objection - I too find tassels classy. I have color 8 tassels with antique edging (BNelson).
However, the gent suggested he had a hard time finding slip-ons that fit, save for Grant lasted models. That fact, combined with various persons' struggles with the aberdeen, was the rationale behind my advice suggesting he retain both Grant lasted models, neither of which were tassels. Personally, if I were him, I would get a black shell tassel over the split-toe in question, but that wasn't the issue.
As for the "dressy" factor, I maintain the split-toe slip-on versus the tassels slip-on is mostly a toss-up, with a slight edge to the tassel. Having said that, the gent could wear either shoe with essentially any style of outfit save for a suit. I would wear neither with a suit. Indeed, I would not wear any slip-on with a suit. That, for me, is non-negotiable. Others see it differently. That is okay with me.
