'Tis this one, which is shorter than it looks in the picture and has browns, teals, greys and purples in it so goes with lots of things.
For tops, I'm a 32F so also don't go for the baggy chunky tunic styles which are everywhere atm.
I like a neat little cardi with a scoop-necked vest under, or there's a lovely drapey-necked top in Gap atm which flatters the top half without adding inches.
I actually have started to wear clingy polo necks occasionally as well; as long as they're fine-knit and fitted and you wear a bright necklace or scarf, they're not too 'look at my boobs everyone!'
I think an open-necked blouse over a v-neck jumper looks nice in a kind of preppy way as well.
