Juicy Couture Sizing

[VollywoodHampires]

I’d really appreciate some help with sizing for a velour tracksuit top that my DD has asked for as a present. I’ve looked on the web and get mixed messages, some say their sizing is true to size and others say they run small.
Usually a size 12 with a 36DD bust, she doesn’t want it too big or too fitted, would you go for a medium or large please?
Much appreciated

back in 2006/07 i was maybe just under 8 stones, 5ft 2 and i wore a small.

Thanks @Mrsphilmiller

My daughter has asked for one for Christmas, shes an 8 would you size up. Like your child she doesn’t want to tight but not too baggy
