I think the outfit you have chosen looks very smart and professional... Very suitable for a presentation and will definitely give others a good impression of yourself.
I wouldn't unbutton your shirt too low though, as not only will it tarnish your look... It will also have all the men staring at your cleavage, rather than actually paying attention to what you're saying! lol
Seriously though, a good choice of outfit... And good luck with the presentation! :o)
As fantastic as link two is... go for buttoned up! They (SHOULD) be focusing on you as a person, and evaluating your people skills and experience. Don't give any distractions. Guys can be VERY shallow!
well if you're looking to turn heads then unbutton it, the cleavage would get them to pay attention to you lol but I don't think its very professional so I think you should just go with all buttoned up. I think the outfit is very fitting and you look awesome, so all you need now is to walk in and you'll do well ha ha :)
button the shirt up the whole way (even having one button undone makes it look like you're trying to use looks to get ahead, which will mean most people then won't take you seriously) and you'll be fine
make sure heels are not to high, no 6" heels, but maybe a 4", keep the buttons buttoned, more professioanl, says I'm not here to show off my body & send the wrong signal, I'm here to look suffisticated & intelligent, I'm here for a presentaton,not a date! good luck
I like the outfit it is nice and makes look great, while being classy. I think you should go buttoned up to be taken more serious, if you don't want that then one. Two is way too much. You have great legs.
It looks good. Just be sure to do a better job tucking in the shirt becuase it looks a little sloppy in that photo. Leave all the buttons done up (looks more professonal) because you can see your bra or cami with one or 2 unbuttoned, and whatever you do, don't unbutton 2 it looks very skanky.
Hmm a lot of men will attend and you're debating if you should unbutton one or two buttons... If you want to make good impression and be taken seriously, then do not unbutton any buttons. Go with link 2 very much lady like.
