Size Guide for The bonniemob Baby and kids clothing

women's size chart


All bonnie mob garments are machine washable, unless otherwise stated on the garment label. 

We recommend that you do NOT tumble-dry bonnie mob products. As most of our garments are knitwear, the heat from tumble-drying can cause fading, shrinkage, and may reduce the lifespan of the garment's quality. Any products that can be tumble-dried will indicate so on their care label. 


Please ensure to wash any denim/ indigo garments SEPARATELY (on their own or with similarly dyed garments) before wearing. Due to the dyeing process, indigo dyed garments may shed some of its colour during washing, but this should stop once it has been washed several times. The bonnie mob cannot accept any liability if you do not comply with these instructions.
