I've worn it a few times, but there are no noticeable stains, and it's still in good condition. It's stretchy, the fabric is sturdy, and I think it's easy to put on and take off. I really recommend this series. (^^)♡ The size is around 100. This is a used item worn by my child. Please refrain from purchasing if you are sensitive to used items. #zarababy #petitmain #pairmanon #futafuta #HMbaby
