I've had no luck finding 1X or 2X or 3X nursing tops secondhand. I've tried to find a supplier or a brand that I could add to HEA but I've had no luck. And I think this is a problem.
Until recently, only Motherhood Maternity sold plus sized nursing and maternity apparel in Canada. Early in 2018, Thyme Maternity started to carry plus sized maternity clothing and nursing tops. This still doesn't leave you with many options when it comes to your wardrobe choice or the price of your clothing.
