Shenae Grimes prius tank top 90210 tv show set

Shenae Grimes is such a natural beauty, so we're going to excuse this frumpy outfit...

The 90210 star arrived on set Tuesday looking ready for bed - not ready to work! She kept it a little too casual in sweats, a tank top, and slippers, but we're guessing she headed straight to the wardrobe trailer to get camera-ready!

The 22-year-old actress is usually such a trendsetter... she recently even turned her personal website into a fashion forum to get interactive with her fans!

"I'm going to be uploading pics of my every day outfits for those interested, if you have any questions or comments about styles you see, would looove to hear your feedback!" she wrote on her blog March 9.

We bet her fans didn't love this look either!
