A leather dress is perfect for these in-between seasons where it's too warm to wear a sweater dress and too cold to wear a sundress. And as long as you keep the silhouettes and colors simple you won't be overdoing it by wearing leather accessories.
Leather is cool because it adds an edge to your ensemble, leather is not cool because its literally made out of animal skin... but thankfully there are lots of alternatives that imitate the texture and feel of leather that don't involve hurting any animals. It's hard to resist buying any leather goods at all, but even if you do- minimize the amount of leather goods you buy.
I got the dress from H&M a while ago, so it's out of stock but below are several others that are perfect for spring.
