A "cute top and jeans" is the epitome of casual dressing.  I can't imagine how many times when I've asked someone what they're wearing to a casually-set venue, that's how they replied.  It's basically the weekend uniform.

This lace paneled top with bell sleeves c/o Shein.com screams spring!

I'm completely crazy for anything with sleeve drama right now.  And this is the perfect weather for this top.  I don't have to worry about cramming or crumpling my sleeves while trying to push them into a coat or jacket.
