    Stretches and loses support in 2 months

    Loved these at the beginning, but they quickly stretched out even with irregular wear.

    Size up - maternity

    I bought these based off of the maternity section on the Knix website. I was about 30 weeks pregnant when I got them and I am in between a medium and large so I want for a large. I found that the underwear rolled down a lot so it is probably on me for not ordering the proper size. I am now postpartum and still have the same issue. However, the material is amazing and super comfy! I wish I ordered one size up in the time frame Knix gives you to do so!

    Fits small

    I ordered the post partum kit vase don the sote sizing and both my bra and all 4 pairs of underwear are small/tight. I don't know if I'll be able to wear the bra at all, but im going to attempt to squeeze into the underwear. I'm past the return date as I ordered them a month th before giving birth, and was unable to confirm fit before I needed them. I'd recommend sizing up, and/or double checking fit as soon as you get them so you can exchange immediately as needed.

    Hated these

    I bought 3 styles all the same size...these I had to toss because they were 2 sizes too small....all labels read the same size...these just were wsy too small....the other 2 styles fit like a second skin....and function as they were designed for....bought 3 more pair before I tried these because I liked the beige ones so much.....very reluctant to purchase anything else in their product line.....
