Hi Amanda! 
Welcome!
Ah, winter…since day light savings time…it gets dark here about 4:45pm. Arg, I hate it, lol.
The boys have made excellent suggestions. 
I’d start with Instant Shine, Instant Openness and Instant Sexiness A and/or Instant Sexiness B.
IS/A has a more alpha-girl feel to it and kinda makes ya wanna strut your stuff, lol. Yeah, baby! 
IS/B has a still confident but softer kittenish vibe to it, think Marilyn Monroe. It depends on which feels good to you, the situation in which you’ll be wearing them, and the targets you want to effect. A lot of us use both.
This thread might shed a little light on the subject for you.
Have fun and I’ll see you around the forum!
