Could you wear pants that are stretchy (thinking a stretchy twill) so they have some give to them, but that shrink back to looking more like slacks? Or just generously-sized casual slacks? (generous in the hips and buns, I mean)
For the tops, what about...
(a polo with 3/4 sleeves)
(a Tee with V in back and front)
(peasant blouse too casual? I love the roominess of it, but bending over is dangerous)
(but not so "come hither" as this. Don't know what this style is called for sure, but something a little more 'discreet' would sure be comfy)
I'll keep looking. Peasant blouse isn't quite what I'm thinking, but it's in-between that and that last V-necked thing. Almost like what they wore in the 70s, the white muslin with white embroidery on it with a keyhole neckline. I'm sure you have seen them...
Kinda like this, but not quite so billowy: http://www.coldwatercreek.com/produc...d-blouses.aspx
