LJ Fairy-- Fashion help, please

So, I purchased the following dress for the holidays-- it' a classy shape without being too frilly-dressy. Considering my shape is an exact hourglass, I figure it'll flatter my waist while being a little more forgiving 'round the bum. I don't want something that's tight all over--if Kate Winslet can't do it, neither can I. I mean, she doesn't look bad, but she does look hippy, and as she is Kate Winslet and in ten times better shape than me, I'm not gonna chance it. So, an A-line cut it is.



I'm just not taken with the white belt, though. I was thinking maybe silver or red-- wide, maybe an obi style. Red belt with hook, red obi, silver obi. I'm a little nervous the obi style will add bulk, but I generally like the look and don't want anything patterned. I'm going for a sleek, classic look to be paired with satin heels and Cuban stockings.

So, thoughts? Help a girl accessorize. And pray I don't need a bra like this one-- it comes in my size and looks interesting in theory, but also like it could be the source of some unnecessary hide-then-peep.

In other news... shoes. One day I will own a pair of red heels, I swear. Oooh, red Ombre. Good girl sexy. Lick 'em hot. Just add whip.
