This bodysuit material and finishings are of very high quality.
Compared to more common brands such as Carter's (which I think usually sizes a little large), it appears true to size but it is slightly stretchy to get good mileage.
The material seems to be very confortable for baby and keeps its claim of helping to control skin temperature. The long sleeves offer good protection against the sun.
As it is very light, fitted and quite plain, it is ideal for layering; I just wish there was a larger choice of color.
I have had a black one for 3 months now and it looks like new, after regular wear and many washes.
I am recommending this bodysuit and I will purchase the next size up without hesitation.
