Ive had a similar experience when buying a bathing suit from MicCostume as someone else on here. Last month I had purchased a Demon Slayer bathing suit for around $37, with shipping included, and it showed a range for the arrival date. These dates were from July 29th - August 5th, and it's currently August 9th and no package has arrived. I had recently contacted the company about this and I did receive a reply stating "We are so sorry we have not sent this parcel to you because we have not received your reply about your order. So are you willing to proceed with your order?". I was very confused after reading this because I had already purchased this item, I'm not sure what I need to reply with to get my order. After reading the message I will say I was angry with them because they haven't even shipped my item. I contacted them afterwards and said that, yes, I would like my order because they had already taken the money from my account. I'm currently awaiting for an email back from the company, but from things I keep hearing about this company I wouldn't suggest buying the bathing suits, maybe other products? I haven't ever ordered from them before so I don't know what products are good to buy that won't get you scammed, but hopefully to future customers they'll know what to buy and not to buy. Overall I'd rate the company a 4/10, just for the reason that they replied to my email.
EDITED: Luckily I have gotten my bathing suit, after about a couple weeks after emailing the company and accepting their process of sending my package, it has arrived. The downsides of this company would definitely be the fact that you apparently have to message them to state that you want your package to arrive, even when you already paid. When I had to do this I was purely convinced that I had been scammed out of my money, but after messaging and confirming they said i will receive my tracking on the package. I had recently been looking on their website on my order to find out that I had gotten my tracking number and was able to track my package. After all that I received my package at the end of August which I had emailed them a little into August. With this all settled I can agree that the website is not bad and my bathing suit came the way I wanted it, but I'd definitely say to email them after noticing your package hasn't arrived. Although I don't know why some have a difficult time contacting them, I do recommend contacting them whenever having a difficult time with the company or any for a matter of fact. Overall I can say that I do change my rate on the website by one star just because I found it very concerning having to message them saying you want your order even after paying and them taking your money.
