Embroidered Bouclé Knit Jacket

Bought this jacket and matching dress in size 2. Dress arrived first & fits beautifully. It’s possibly a tad long so may have it hemmed but was waiting to try with jacket before doing so. Jacket arrived today and is a lot thinner than expected but thought that may be better when wearing over the dress. But the jacket — labeled size 2 —doesn’t fit at all, far too tight in shoulders & arms, barely fitting over a tee. It’s more like a 00 than a 2, very odd for St. John which is known for running large. Super disappointing as it’s now sold out in larger sizes. It could be true to size in larger sizes but definitely not in the 2
