Has anyone ever bought Puma baby clothes?

I bought a Puma track suit for my LO (originally $50 for 20 bucks, yeaaah Marshalls.) Anyhoo...is their 12 Months 6-12 Mo. or 12-18 Mo? I bought 12 Months thinking she'd wear it springtime when she turns 12 months...the when I got home I remembered she's always a size behind so when she gets in 12 months it will be summertime and 95 degrees ever day, unless it's 6-12 Months in which case she can wear it in springtime.
