## Customer Reviews

### ⭐ 







  
  
    Very poor quality
  

*by D***L on Reviewed in the United Kingdom on 3 January 2017*

I've had a few OnePiece onesie's and this one was very badly made. The red shoulders are made from red plastic and the print on the upper body is a screen printed plasticised paint. Also,  the lining was of very poor quality (the kind that would bobble in no time at all. I was very disappointing with the quality and so returned it the next day.

    Better than my John Lewis onesie
  

*by P***W on Reviewed in the United Kingdom on 24 February 2016*

Bought XXS size as a present for my 5ft tall wife. Arrived quickly in the original Onepiece packaging. She was a bit dubious about a onesie at first.... But the fit is great, it's super warm, and the pattern is good. She loves it.Happy wife = happy life.

### ⭐⭐⭐⭐⭐ 







  
  
    Classic and Quality
  

*by S***Y on Reviewed in the United Kingdom on 27 January 2016*

What more can you say, leading quality onesie. Bought this to replace an exact same one from several years ago for my student daughter and was pleased to see the quality has not altered over those years. Was pleasingly much cheaper from this supplier than ordering direct from OnePiece.
