Briefly noted...
Proof positive that it is more than possible for a woman to dress in a way which is modest, yet undeniably alluring! It's not necessary to "let it all hang out" to be attractive, and conversely, it's not necessary to dress in a "frumpy" manner to preserve modesty.
See FallenWiki - Gabbe Givens for more on this specific individual, Hermione Cornfield, and the character she portrays... I hadn't known anything about either, until I ran across this picture, on the "interwebz"!
