Mango children’s sizing - runs big or small?

[MrsH201]

Just that really... does anyone happen to know?

Very similar to H and M, if that’s any help

Oh, yes, I think that does help. My son has just outgrown his 6-8 long sleeved tops from H&M, even though he wears 7-8 from Next and M&S with room to spare, so hopefully my having ordered 8-9 from Mango won’t prove as bonkers as I thought it might! I guess I’ll see when they arrive. Thank you, Fivemoreminutes!
