The dress you can get your hands on by TPing over to the Enchant3D mainstore. The dress is only 75L and you get two versions in the pack, black and red. They each have the opposite colour heart on the front and are fitmesh. This should easily fit anyone who is a Standard Size XXS - M or over a mesh body. Please however try a demo!
The necklace is from Oxide. It's the Amarna Necklace and in the pack you'll also get earrings and a hud that allows you to switch up the colours between black, silver and gold. The hud is quite handy as it allows you change individual areas of the jewellery so you can mix up the metals too.
These adorable little Tetris style blocks are the BlockLamps from Little Llama. You get the seven different shapes in the pack, each shape a different colour, and you can turn them on and off with a single click. They are fully mod too so you can make them HUGE or tiny. I was trying to build a Tetris style wall with a piece missing from each row so it looked like I messed up my game and could have a wall full of lamps... it went against everything I've ever known as a gamer! LOL. Still a lot of fun though!
