I can't help myself... I saw these dresses and they were so beautiful, I had to post them. I bought the long one for myself (my nephew's Bar Mitzvah is coming up!). The pink one would be beautiful for a Bat Mitzvah girl. Both are BCBG designs.

Shopping for an appropriate party dress for the Bat Mitzvah girl can be quite challenging. It is difficult to find styles that don't look childish, but don't look too revealing either.  I recently came across these two adorable dresses, which would look beautiful on a young lady (and come in XS sizes). They look youthful and playful, and have no plunging necklines! The first dress is a Jessica McClintock, a designer who is very popular choice for Bat Mitzvah dresses. The second is a Roxywear jersey dress. I love how the designer combined the gold sequins with the casual jersey fabric. Really cute!
