Lancy from 25 Slim Fit A-Line Dress Sleeveless Waist-Cinched Elegant Style Pure Color Autumn New Arrival Womens Dress

Wore it three times and it got a hole. Customer service says it can't be washed? Really, is this about not being washable? I hand washed it, and now there's a hole. What kind of quality is this? Bought many times before, not going to buy this brand again!

The care label says 'do not wash,' but the TikTok live stream host mentioned that it can be washed by hand or machine and is easy to maintain. I checked with another customer service account, and they said it's not washable. Who should I trust? I just want a more authoritative conclusion because I can't accept it shrinking. Other minor issues like slight fading or wrinkling are no big deal as I have a garment steamer. I've already matched it to my height and weight, so it can't shrink any further. I haven't washed the clothes yet, fearing they might be ruined. Please provide a clear and official answer.
