We know that bra-revealing ensembles are hot these days, but we think Jessica Lowndes of "90210" is showing a bit too much. What do you think?

We spotted Jessica in her lacy see-through outfit at The Embassy Club in London last night where she spent the evening partying with friends including DJ Ironik. She returned to her hotel at 1:30 a.m.

Despite this fashion fail, we like Jessica because she does her part for charity.  This winter she and her co-star Matt Lanter teamed up with DoSomething.org to help fight homelessness.
