I do realize a post on this same item was made and i want to clarify that i will only be showing you the RL version, since the SD hotbuys pic was already shown in the post prior to this.
The real life version is from Chloe Sevigny for opening ceremony (just like some of the other items):
(sorry for the bad quality pic)
For the blouse you can go here. if it does not work (which it should) simply look under the new items category because for some reason, although the HB was released, it is not currently in Decades, its shop.
