Yes, I understand about the double breasted jackets just looking too boxy. They do on me too, unless there is a good belt to draw them in.
That grey warehouse jacket + oasis trench is nice and I thnk I may end up trying that on those items myself!
Regarding the dresses, I think some tunics are just too toppy - you're right. The ones that are supposed to be dresses I think look really good with chunky healed shoes (platform maybe?)
I personally like shirt dresses but some of them have too many pockets etc and I feel like there can be too much going on (around the boob-area especially) That and they're not as "in" as they were (but I'm sure they will be again soon!)
You already have a good boot collection so there is always the staple a line knee length skirt or even shorter A-line for you (shame to hide your legs!) For me, short skirts and knee length boots can look good, but can easily look hookerish. The flat boots and a shorter skirt may look younger and less try-hard. Though again a shorter skirt with chunky healed shoes would look gorgeous. Sorry, back to the boots how do you feel about the cropped trousers and boots look? If the boots are nice and high then I think you could get away with it, otherwise you may think it chops you up into small sections and therefore gives you a less-tall look.
There is always the knitdress/jersey dress that would look nice with shoes and boots.
I think this dress is cute and could be worn with poloneck (may not look good with big boobs though?)
