Let me start by saying I was skeptical about shapewear in general, but these panties changed my mind. The first thing I noticed was how soft and breathable the fabric is - it doesn't feel like you're wearing a corset at all.
I wore them under a tight cocktail dress for a wedding, and wow - instant hourglass figure! The high waist really does smooth everything out without creating awkward bulges elsewhere. What surprised me most was how they stayed put all night - no rolling down even after hours of dancing (and trust me, I tested this thoroughly).
The sizing is tricky though. Like other reviewers mentioned, you might need to size up. I normally wear medium but went with large based on reviews, and it was perfect. The groin area is snug but not uncomfortable - just gives that extra smoothing effect.
After several washes, I will say the lace trim does start to fray (I just trimmed mine off too), but the shaping power remains intact. They've become my go-to for date nights, work presentations (hello confidence boost!), and anytime I want that extra polished look under clothes.
The only downside? They're so comfortable I sometimes forget I'm wearing them until I catch my reflection and think 'Dang, when did I get this waist?' If you're on the fence about shapewear, these are a great starter pair that actually delivers what it promises.
