I've been looking to get my daughter some new long sleeved tops and decided to buy these, and I'm glad I did. I bought them in size 6-9 months and the fit is great. The material is lovely and soft, plus very stretchy which is an added bonus. There are poppers at the neck, but I've found I haven't needed to use them yet due to the fabric being so stretchy. I'm sure they'll come in very handy as she gets bigger though. Overall I'm very happy with them and would readily buy them in a bigger size when she grows out of them. I'd also like to add that I'm very pleased with how quickly these were delivered to me despite everything that's going on right now. Vielen Dank Next!
