Comfortable But Sizing Consistency Issues

I purchased several onesies from Onesiebuy for family parties and casual lounging. The overall quality is decent and the designs are fun and colorful. The fabric feels soft and comfortable against the skin, which is the main requirement for sleepwear. However, I experienced significant sizing inconsistency across orders. One size large fit perfectly, while another size large from a different design was noticeably tighter. This inconsistency forced me to order multiple sizes to find the right fit, which was frustrating and expensive. Their sizing chart could be more detailed with specific measurements. Shipping took about two weeks, which is longer than expected for standard orders. The product descriptions don't provide material composition details, which would help with durability expectations. Washing and care instructions came printed on the tag, though fading was noticeable after a few washes. Customer service was polite but didn't offer solutions beyond suggesting to order different sizes. The website is functional but could be more user-friendly with better search and filtering options. Prices are moderate but not exceptional. Overall, Onesiebuy provides acceptable products with room for improvement in consistency and customer service. I would use them again if they address sizing issues, but currently recommend checking recent reviews for specific size feedback before purchasing.
