I had my 2nd baby on June 18th, and started wearing Wink Ultimate Belly & Hip shaper when I returned home from hospital (1-day later). I ordered this item in Large while I was still pregnant. Today, I just ordered Ultimate Postpartum Ultra Bikini in size Medium because now the Large is too large!! I started at the largest notch, now I am at the tightest notch. It's only been a little over 2 week and. I love how this shapewear fits. It's very comfortable, and I wear it all day and night (except when I have to shower). I feel almost 100% back to my normal self and I am starting to see my waistline again. I'm sure I'm going to need a size small by the time I return to work in August. Thank you Wink for helping me to get my pre-pregnancy body back!
