Is $200 a lot to spend on a dress?

I know this is so silly, but I've found this dress that I absolutely love. The brand is Myne (You can find the brand at online boutiques and Nordstrom). I've wanted the dress for a couple of years, and I've found it on sale online for $200 (It was originally $275). I am graduated from college and I work in an engineering field at a company in Silicon Valley, so it's not like I'm 16 expecting my parents to pay for it, haha. I'm always so frugal and shop at places like TJ Maxx and Ross, so I'm a bit apprehensive to make this purchase. The dress is 100% silk, so I feel like the price is actually a good value for the product, and I can't find a less expensive alternative. The dress is also an "every-day dress", so I can wear it often to work, around the town, out at night, etc. Does $200 seem too much?
