Longer length tops

[PersephoneParlormaid]

I’m a curvy size 16 and always wear leggings as I don’t feel comfortable in jeans anymore, and I’m not a fan of wide legged trousers, I think they make me look fatter.
So I’m looking for tunic length tops that cover my bum, but I do like them a bit fitted so I don’t look like I’m wearing a tent.
Id also like to try a cropped jumper over a shirt, as wool makes me itch so I need something better on my skin, and I thought the shirt tail could cover my bum.
Any ideas very welcome.

Im a size 10 to 12 but my formerly fat bum is not my best feature so I like it covered. But the tops don't look good if they are too long.
I just Google longer length jumpers/tops and loads come up. I also like blazers, longer length cardigans, longer tracksuit zip up tops etc with shorter teashirts or a nice top underneath.

I think wide leg trousers look awful on most people. I look dreadful im them and really fat even though Im not fat. I think you need to be tall and willowy to wear them. I prefer a kick flare.
