I think I could pull off just jewelry

but its way too soon for that! ha ha
Well, its hotter than hell and the outfits you suggest are great--and totally something I'd wear out to dinner--but in?
Trying to achieve a few things--
Casual but not too casual--ie; Denim mini ok, denim shorts not.
Show off the bod a bit more but still be classy.
Try to survive the heat--I live in a classic 1930s apt--w NO AC!!!
Not have any awkward clothing moments--ie: i always end up, after dinner and wine, sitting on the floor in front of my stereo playing DJ Amy ... denim mini not good for that.
OH, and can almost guarantee he'll be wearing button down and shorts....
