too much - 过头了
I know you have a real unique style. But don't you think that jewelry is a little too much?
Too much? Not at all. This is how I roll。
over the top - 夸张的
Taylor Swift's performance at the 2013 Billboard Music Awards was quite over the top, but I enjoyed it very much.
A: Did you hear? David hired 100 dancers to stage a flash mob proposal for his girlfriend. I think that's a bit over the top.
B: Aww I think it's romantic. Love makes people do crazy things.
overkill - 过度的，超越正常标准了
Getting dressed up to go to a Lady Gaga concert is appropriate and fun. But actually dressing up as Lady Gaga to see Lady Gaga seems like an overkill.
打扮得漂漂亮亮去听Lady Gaga演唱会是很得体也很欢乐的事。可是打扮成Lady Gaga的样子去见Lady Gaga好像太过了。
Wearing a few rings is alright. But wearing rings on every finger is a complete overkill.
