Love Notes

Best bikini hands down!

Best bikini in years! To say Im satisfied is and understatement! I had a custom kind made and it fits so beautifully! I will definitely be ordering another one before the summer, and recommending to everyone! Thanks for knocking it out of the park!!

Absolutely love the fit

I was so nervous about receiving my high waisted cheeky bottom as I have never shown the much cheek before. I absolutely LOVE the fit it’s so FLATTERING and it’s just the right amount of Cheek. I can’t believe I waited so long! Thank you so much for making me feel confident in my own cheeks!
