I find V necks flattering, but I tend to wear quite shirt dresses with thick tights, so lots of leg on display, and v necks can look a bit tarty. Round or scoop are fine - square necks make me look hideous and cowl necks make me look saggy boobed, even in a good bra.
I tried both the Hobbs and Jigsaw tops on this week OP, and found them v v unflattering. I am a 30F. Both tops clung I flatteringly to my untoned (because I am a stranger to the gym) (because I had 2 c-sections) tummy while doing nothing for the norks. Minging. Nothing helpful to add here but was relieved to see your thread because at least it's not just me!
That first Zara one is lovely CharlieFox. I really like the sleeves too. Love the shape of the other two but not the fabric so much.
Remus gotta look on the bright side right?
I've got quite wide shoulders too, so sleeves need to be simple and not cap, or sleeveless. My current top collection consists of numerous H & M vests and a couple of Zara linen tees. And loads of jumpers. Funnily I can wear higher neck jumpers.
The Simone tops work well for me. I also like scoop and slash necks. I don't like V necks unless I have a scoop neck cami underneath - v necks on their own make me look a bit scraggy around the neck, as I have a long thin neck.
