Gray Stripe Silk Blouse

Hmm, this is a nice, simple but chic blouse by Erin Fetherston that is on sale at Revolve Clothing for $176. I probably wouldn't have posted it, nothing about it really catches my eye except... originally $704???? Does it make you look 30 lbs lighter when you put it on? Even that wouldn't be worth $700 to me, holy cow.
