They are the same company, so why are the sizes so different?
I bought 18-24 mo long sleeve shirts from ON for S and he's about to outgrow them. I bought 2T t-shirts for this summer and they fit now and they fit well. I don't know if they are going to last until the end of the summer.
I bought him a couple 18-24 months t-shirts from BabyGap last summer for him and they are too big, but will probably fit him well come summer.
WTH?!
Re: why are GAP and Old Navy sizes so different?
Not only are they different between GAP and Old Navy, they're also different just within the store!
I wear a size 8 at old navy and GAP. But I have to try on 4 pairs of size 8s just to find ones that fit. Some fit way big, some way small. It's crap.
