It’s UK brand called Topshop. The straps aren’t adjustable ones but I used to tie them at the back of my neck which gave it a halter neck appearance. It’s a flowy cami top in a beautiful mauve color. Perfect for layering or wearing on its own during warmer weather. The delicate straps and soft fabric make it a comfortable and stylish choice. Dress it up with a skirt or keep it casual with jeans.
