<-h2->Long sleeve party tops for December<-h2-> Long sleeve party tops are how December gets dressed without reaching for a jacket. This trending collection gathers satin, sequin, velvet, mesh and lace, in black, deeper colour and metallic finishes, with cuffs that flare, shoulders that sit high and necklines that stay closed. The sleeve is the whole argument. It makes the top the outfit rather than one layer inside it, and it means nothing has to be handed over at the door and retrieved at the end of the night. She keeps the rest plain because she understands the balance, letting sequin or high shine sit against something completely quiet. Some are cropped, some fall long over a trouser, and a few carry beading or a ruffle set at the shoulder. Satin catches the light gently, velvet holds onto it, mesh lets it straight through, and lace does something softer again. These are pieces bought for a season of invitations and then pulled out long after the season has finished. Party dressing starts at the top.
