Does anyone know why this Express sweater is $198?

That's too expensive for an Express sweater and I wouldn't know why. Maybe contact Express and ask them, the price is ridiculous for an Express sweater top. Even if it's made out of premium fabrics, the price shouldn't be that high. I'm looking at the sweater on the website now, the price stands out from all the other $40~ price sweaters. It's not made out of silk. I would call and ask.
