Puffed sleeves! I love the idea of getting a split skirt. Seven's look is a bit Country Gentleman (with an extra large helping of ??? thrown in for good measure) so the riding skirt style would be perfect! I really like that whole outfit, honestly. I think it matches Seven's style more than the more formal bodice you linked to (which is beautiful but very formal - and you might need a corset with that style).

That paisley ribbon tie is great, too. A very nice way to evoke the scarf.
