Having considered all the evidence, I find her cute, but nowhere near as cute as my wife. If she's that distracting, there's something very wrong with the other women in the office.
She’s pretty IMO, though that first photo is not really her best in this group (I’d say the last two are).
I’ve worked with prettier women, and it really is not that big of a deal. If it is a big deal, then maybe the rest of the office needs to take some maturity classes or something.
