This white St. Agni Anzu mini dress is crafted from cotton and linen, and features a square neck, slim fit, short-length hem and spaghetti straps. We can totally see Mossy rocking this St. Agni dress back in the '90s. We're fully going for it, throwing it on in search of deep hedonism with evenings of champagne quickly turning into all-night raves, before we roll out of bed and do it all over again.
