I totally agree with BD. This plant is VERY dehydrated. It needs more watering. I'd even add a little superthrive to the water to help get it going. You need to totally drench that plant when you water it. Misting should help some but it needs a total dunking. If you have it in a bathroom, run the shower and let it get completely soaked. The only other idea is to repot it in something that retains moisture a bit better like clay pot. I have several orchids in baskets and they need way more watering than any of the ones I have in clay pots or they start to wrinkle like yours.
