Lanvin at ASOS

€59.71
ASOS Exaggerated One Shoulder Pencil Dress

Today i wanted to find out how original is the Lanvin collection at H&M. The question is: can we find similar dresses anywhere else if we can't make it the 23th of November?
This is my first find the puffy one shoulder dress. This one is by asos; compared to the Lanvin one is pretty similar, do you agree? You can choose between three colors: mink, coral and black. The price difference is not this big, it costs 30 Euros less than the lanvin one but you can buy it if you can't get the lanvin one
