Beautiful and oh-so flattering, this long sweetheart a-line prom dress by Chicas is ready to give you a spectacular edge. Crafted in shimmery satin fabric from the surplice sweetheart neckline to the hem, this long special-occasion dress gets a fitted look with thin spaghetti straps that tie into bows at the shoulders. In misses and some plus sizes, this long formal dress has a long a-line skirt that opens in a side slit before ending in a sweep train. At under $100, you can wow your friends at prom, galas, and other formal events without busting the budget.
