Highly recommend this onesie! Sarina was kind enough to ask about our pup Finley's dimensions to ensure that it was a proper fit. She was very efficient in getting it delivered, even while it required some modifications, and asked all the right questions. The entire process was seamless. The onesie came quickly and efficiently and fits like a glove! I have tried (and returned) many sweaters in the past but this one will definitely be a staple during cold Toronto winters. It is great as an underlayer and also for rocking in the Fall. Thanks, Sarina & Cooper!
