ombre dress blue Bebe Women's Asymmetrical Dress, Medium Lined Shell Primavera Couture 4102 Size 4

This black cocktail dress exudes modern sophistication, crafted from a luxurious crepe bodice that seamlessly transitions into a breathtaking floral lace appliqu skirt

Completes at a versatile below-knee length

I think an OCBD or polo shirt would work better with the level of formality and provide that extra collar (even if the shawl cardigan somewhat mitigates this problem)

This long-sleeved mini skater dress from Boohoo is a versatile addition to your wardrobe, perfect for various casual occasions

This is so pretty that you'll want to wear it to another event down the line
