This two-piece Rachel Allan 7505 prom dress is made of matte satin and features a full ballgown skirt and a scoop neck embellished crop top. The cropped top is fully beaded with a pattern of multicolored crystals and sequins, which is repeated again on the skirt waistband. Tank style straps round the shoulders to meet a deeply scooped backline. For the skirt, the A-line silhouette is nice and roomy, with pleats at the waist. It reaches floor length and also boasts hidden pockets on the side seams.
