along the chunky accessory trend i have found a few items which i think can easily go well with one piece dresses or black tops and achieve a statement look :
Tommy Hilfiger (image from Stylesight)
Earrings - Topshop
Necklace - Topshop
Cuffs & Choker - Reiss
as for myself... i am still looking for the perfect simple metallic choker. it is HARD!!!
