Not calling authentic only because I don’t have receipt or tags; however, I’ve had 4 of these suits and these fit all criteria from ChatGPT too. Versace sizing is 1-5 with 1 being xs and 2 being a small. These do run snug but there is elastic component. I am 5’6” and I can wear both the size 2 and size 3. I included a photograph that shows my other Versace suits and the similarity in the authenticity. Versace women's two-piece bikini. Vibrant turquoise blue fabric with gold Greek key trim and Medusa emblem. Triangle top and mid-rise bottoms. Luxurious branded hardware accents. Two-piece Versace swim set in vibrant turquoise blue. Please note the actual color of this suit seems to be more “turquoise sky blue” and these photos are appearing slightly more royal blue. Please do online search for actual color if unsure. Versace does a 1-5 sizing scale. This high rise suit is size 2, which equates To a Versace size small. Please note this style does run snug. Retails for $500. Authenticity cannot be confirmed because I am not first owner and the long white QR auth tag was removed (very commonly due to irritation) by prior owners. However, I have 3 other Versace suits and the quality and design is all consistent with authentic.
