Lindex kids sizing?

[wtftodo]

Does it come up big or true to size? looking at PJs for a tall 7 yr old (around 128cm) who wears 8-9 or 9 other brands - should I size up to the 134-140 size or will it drown her?

I have tall children and this is one of the few shops that they wear their true size. My 4yr old has grown out of 5-6 next for example but 5-6 lindex is fine, the next size up was huge on her
