Such a gorgeous dress from Oh Polly. Worn once on my bachelorette. I didn't wear the removable neck strap. The fabric has a slight stretch to it and is fully lined. The sleeves aren't attached/ are separate. I had no issues with them staying up. The detail on this dress is unreal- the pearls and beading are so pretty. I got so many compliments. Fits XXS- XS. Size 0 US and sold out online. Description from website: Fun and flirty, Soho was designed for girls who know how to command attention. Cut from our pearl and bead adorned fabric in two lustrous colourways, Soho features a bust flattering cowl neck with asymmetric, ultra thin straps that cascade across the neckline. With our signature built-in corsetry that works to cinch your waist, Soho is a bodycon design to the waist before the skirt falls to a thigh skimming a-line design. Complete with fully embellished, detached long sleeves that flare at the wrist, Soho has everything you need for your new season, party girl wardrobe.
