I ordered a onsie which arrived promptly but sadly was too big. I returned it using the free service, the customer service team expedited the exchange and my new one is on its way already - fanta

Their sizing is ridiculously incorrect, and when you inevitably have to exchange or return, they charge absurd shipping costs, take a lifetime to respond to emails and process refunds… and in my case, they then shorted me $60+ on my refund, and now have to wait for weeks again to get a response.

The jumpsuits themselves are decent but not nearly worth what they charge, many hundreds of dollars for an extremely average product that should cost a fraction of the price. Absolutely not worth it, and customer service is terrible. Buyer beware

I have tried to contact them for weeks

I have tried to contact them for weeks! 3 different emails. And they don’t respond. I have a size xs I bought last year and it fits perfectly, I bought a new one now and I measured it too before buying but it was sooo small. So I needed a return and exchange to a size bigger. THEY ARE IMPOSSIBLE TO GET IN TOUCH WITH! I don’t have any return label to send it back either?? Now I have a one piece I can’t even use!!! So much money!! Stay away.

Terrible Experience!

Ordered before the holidays. Paid for expedited shipping. Never received my order and still never received a response to my inquiry. Do Not Order from this Company!

What is going on OnePiece

What is going on OnePiece, your designs are not as good as they were years ago. Boring, bland and uninspiring. They used to be so funky, do you have a different designer, if you have, sack them. Really wanted to buy a onesie in the black Friday sale, but found nothing that stood out for me. The denim products were nice, but only one colour, acid wash, could do with a dark or medium denim colour as acid wash went out in the 90s. I ended up going on Vinted and buying pre loved older Onepiece onesies that people were selling at a fraction of the price. I bought a lovely denim brand new with tag one for 22 pounds, bargain.

I'm very grateful to customer service, thanks Kajsa!

This time I didn't get the size right: the onepiece I had from them was from years ago and I got a little confused (well, quite a lot) and also, I wanted them to arrive in time for my wedding. It's going to be the onepiece I wear that day! So, in my rush, I ended up messing up the order.Even so, I'm very grateful to customer service, especially Kajsa, who made everything so easy for me: the return, choosing the right size... In short, thanks to them, We are ready for the wedding with our onepiece (my fiance too)!Thank you very much!

Problem finally solved

Update the 8th of August.After my insanely negative review below, I finally heard from Onepiece.I guess they are legally apologized for not responding.I keep my review, though, because I Think it might be useful for people to know, that there might be a problem here with e-mails bouncing.I was actually getting really furious, as my review shows, and I felt cheated, manipulated and stupid.But I just received a very pleasant e-mail with instructions and a returnlabel.@ Onepiece: I Will highly recommend, that you start sending returnlabels with the items, when you ship. Other stores do that, and only withdraw the money for the returnlabels, if they are used.In that case you wouldn’t risk that your costumers would feel helpless for not being able to return an item. My old review: RUN AS FAST AS YOU CAN! DON'T BUY ANYTHING HERE!!They do not respond, when you try to contact them. If you are so lucky to get your ordered item, it is impossible to reach them to ask for a refund, when the size or colour is wrong. This firm sucks. I hope they will burn in hell.Update.No. That isn’t the case. And I have been writing to you over and over again on excactly that email-address. I have tried to reach you on support@ onepiece.com several times. No answer what so ever. Also tried this emailaddress: vip@ onepiece.comBut do not get any answers, not even a confirmation-email, that you have received my message.Stop trying to blame some false webpage for your own failure.

Johnny at OnePiece customer care was awesome! With new tariffs in place I think everyone is a bit confused. Johnny researched my issue quickly, gave me several options to resolve my issue and made sure everything was worked to my complete satisfaction. Bravo!!!
