Are pearl thongs actually sexy?
If you are heterosexual, you are asking in the wrong place.
If you want proper input you need to get a cross section of men to tell you what they think.
Also bear in mind that sexiness is very subjective and an average view doesn't necessarily equate to the man you are dealing with.
Most men (an average) would find a young healthy toned woman with large breasts attractive. There are plenty of men who only get turned on by different things - very slim women with small breasts, very overweight women and so on. For every extreme, there is usually a dedicated porn stream somewhere.
You are totally wasting your time asking women what men find sexy. Even if you get the "well my husband likes it" response, bear in mind that in long term intimate relationships white lies abound -
I get turned on by dirty great granny pants but I can't bring myself to tell her.
She was so proud of her new underwear, I thought the right thing to do was pretend I loved it but I've always hated red/black/white underwear as it reminds me of prositutes/death/virgins.
I don't care what she wears but I act like I do because she takes so much time over it and it matters to her
