Hottest of all the wives

I don't think Lynette is bad looking, but she's probably the least attractive of the main wives. If I was a guy I'd probably go for the looks of Bree.

And you include Renee as a housewife but not Susan or even Edie? 

Susan and Gaby but Teri Hatcher gets extra points for Lois and Clark.

My top would be a toss up between Brie and Susan. Susan was really cute, even if she did often annoy me. And Brie was just a classic beauty.
And to be fair, Lynette (Felicity) did not look her best on this show.
They really downplayed her looks. She has been very pretty in other things. But still not on the level of some of the others.

Just doing main characters whether or not they were married-

1. Edie (the character in general was a total sex goddess)
2. Gabby (ditto for above)
3. Bree
4. Susan

Gabby. She looked absolutely amazing. In the episodes before they started with the Alexandro nonsense she looked like a goddess.

I look like Lynette

1. Gaby
2. Brie
3. Susan
