Long tops to wear with sports leggings

[flowerfields]

Looking for recommendations for longer length slightly loose fitting floaty style tops to wear with gym leggings etc...ideally darker/neutral colour with sleeves.
I tend to wear black gym leggings most days and need something that covers my bum and isn't tight fitting so I can layer underneath.
I can't seem to find anything that fits the bill and would love some ideas

seasalt do a lot of that type of top. they look odd on me

Primark have some thicker jersey type ones that fit this. Work well as they are a bit longer at the back too so definitely cover the bum.

Hopefully they will open again in Dec

Thanks both

I got one from Uniqlo in their Airism range for workouts. Properly long enough to cover the bum, which is surprisingly hard to find.
