    I was skeptical...

    But these really are as comfortable as advertised. And my husband LOVES them.

    Sexy and confident

    I ordered the matching bra and I am beyond impressed. I feel so awesome wearing it. I’ve not washed it yet so I don’t know how it will hold up but first impressions are 10/10
