My DD wants Victoria Secret shortie pj's for Christmas. I've ordered them from Next in small and medium so I could gauge which size is best. However they've arrived all tied up with a lovely bow that I don't want to undo. So my question is what's the sizing like? Is small 8/10 and medium 12/14? do they run small? Personally I like things a bit loose but I don't want them to swamp her, she wears a size 10 normally but has chunky upper arms.
