Things I discovered include that tops sized 14-16 fit me well in most shops, although a lot of 16s are too big across the shoulders. Scoop necklines are good, squared scoop necklines (I have no idea what to call those) look great. Vertical detailing like buttons or piping are great, frills, tucks, flounces and ruffles are terrible. I can wear some medium-larger prints and look great but smaller prints make me look like wallpaper. Nowhere has skirts/dresses in right now, and the tops that are out there tend to look like they're designed to look good with jeans. I'm sure they do, but I don't own/wear jeans. Most of the stuff out there has sleeves that are too long and hems that are too low for me. Hems on shirts which are longer than my hips pull back in under my belly and emphasise it, but shirts that end an inch or so below my belly button look good on me.
That sounds like a lot of really useful information (though it's always frustrating not to find anything you want to buy). I tried searching for day dresses on a few websites (am I right in thinking you're in the UK?) and I think I found a few that fit (some of) your criteria - do you like any of these?
navy knitted dress
dark pink scoop neck dress
blue flower print jersey dress
red scoop neck jersey dress
white scoop neck knitted dress
blue-grey knitted dress

I think, like rowan said, blazers are pretty much like suit jackets, but maybe in different colours or sometimes different fabrics? (e.g. corduroy, denim, leather). There are some examples here and here.
