Predict-a-Gown: What Will Christina Wear? | Christina Aguilera
The biggest change in Grammy nominee Christina Aguilera's red carpet style? Clothing is no longer optional. Gone are the days of the Dirrrty trifecta – bra, panties and chaps – and in are old Hollywood-style gowns to match the retro sound of her CD, Back to Basics. So which siren style will she wear to the Grammys? Here are picks from PEOPLE's StyleWatch team:

• If she wants something glam – but still a bit racy – Aguilera could slip into this see-through crystal-encrusted sheath (right) from Roberto Cavalli, who designed her tour costumes.
•But if she wants to show less skin, she could try this shimmering black gown from Fendi.
•For a real switchup, she could go short. We think she'd look flapper-fabulous in this fringed Zac Posen or this glittering Behnaz Sarafpour.
