Homecoming dress?

So I went to begin looking at homecoming dresses for the hell of it because I was bored- and I found this beauty! It's $410. The boutique only ordered one in this one size and it fits me nicely. I'm going to be a senior and I've had conservative dresses all three years for homecoming. I'm shy and quiet and I kind of want to buy this dress to blow everyone away with something they'd never expect me to wear. Opinions? Too slutty? Gorgeous? Please let me know! I haven't bought it yet. ☺️
