You can view Lucy in her blue peplum & exaggerated bow detail dress here.
You can buy Lucy's dress here from the The Pretty Dress Company website, or here from the Love Lucy X website.
I have blogged about Lucy's dress before, both when she wore it on an episode of The Only Way Is Essex, and when Amy Childs wore it, and you can view those posts here and here.
