Pure Cotton Cardigan (3 Months - 5 Years)

I bought this cardi in the 6-9 month size in store to go with a 3-6 month dress which I purchased at the same time as when held together they seemed to be about the same size. On returning home and comparing the garments more closely, I realised that the cardi was too small for the dress so I ordered the next size, 9-12 months, online. However the 9-12 month size is exactly the same width under the arms as the 6-9 month size and both are smaller across the chest than the 3-6 month dress. What a waste of time! Nice design, nice colour, hopeless sizing!
