Harriton M420W - Black - Ladies Pilbloc™ V-Neck Sweater

I like this product but when I ordered and try on the different colors in the same size, I get much smaller sizes that dont fit. For instance I ordered a navy sweater and a green in the same size, and when trying on, it is very apparent that they are at least 3 actual sizes different. The tag shows the correct size and same size on both. Makes it difficult to continue to order as I am not sure of what I am actually going to get and waste of money/no return policy.
