Ujena tankini top sheer sexy honeymoon appropriate

Many years ago I was obsessed with this tankini top and finally bought it. It’s soft, sheer and sexy and the draping part has a little sparkle to it. But the top is sheer and a bit see-through and I never had the courage to wear it. I think it might be a 1x but it seems to fit between a L and a XL. I’m going to say size xl but not sure. It’s stretchy - the band that goes under the bust is about 15 inches unstretched.
