I was sorting LO's clothes today and noticed a vast difference in onesies. The sizes are completely different, most specifically, the new Gap onesies. They've switched them to a thicker fabric this year, but they're so small! My DD is like a sausage wearing them, yet she fits all her other 0-3 onesies.

Here's a pic of some of her more common onesies:
Thickness: Gap & Small Wonders are pretty close in thickness with Vitamins in 3rd place.

(Back to front)
Vitamins Baby: wide **widest pictured
Small Wonders: wide
Precious Firsts by Carter's (Target): slim, very long **longest pictured
H & M (2-4m): slim
Little Me: normal
Baby Gap: short, thick **shortest pictured

What's your favorite brand of onesies? Do you prefer them long or wide, thin or thick?
