You can view Rochelle in her chic strapless little black dress & arrowhead necklace here.
You can buy Rochelle's dress here and her necklace here, both from the Celeb Boutique website.
I have blogged about Rochelle's dress before, when Billie Faiers wore it in red & when Chloe Sims wore it in white, and you can view those posts here & here.
