Super excited for you, Glitter!
On the game of lingerie, I would say... find something YOU feel sexy in! It makes a world of difference. If you absolutely love love LOVE that bra and panty set, then get it! Not so keen on that other babydoll? Don't. My main way of purchasing things like this is basically that criteria: If I'm not completely sold on it within the first five minutes, or after trying it on, I'm not getting it. But, if it does everything I want it to and I totally love it, even after trying it on...get it!
Most women think black is sexy, but I would say that it tends to look fairly harsh with most skin tones. Try things like tan, red, and purple. They are often flattering to most people (unless your skin is the same colour as the tan, then that's kinda weird). Please be sure that you are getting a bra that fits you correctly! I don't even trust people in the stores anymore. I've been told by a few ladies that I was something like a 38 DD... and those bras had me popping out EVERYWHERE! I'm actually a 30 I, so I'm not even sure where they got those numbers from. It was crazy.
Basics of bra fitting: Measure your waist, right where the band of your bra would fit, in inches. This is your band size. Then, measure the fullest part of your bust. The amount of inches different it is from your band size (in my case, 10 inches) will indicate your cup size. So, A B C D DD E F G H I - ten cup sizes, I am an I cup.
You'll want to make sure your band sits comfortably, without wandering upwards or cutting into you. The straps shouldn't fall down, nor should they drag your band upwards. Remember, the band is what gives you support and lift! The straps are just there for shape.
Umm, anyways. Didn't really think I'd get into the world of bra fitting! But it's important!! You want to feel awesome and sexy and fantastic! If bras don't make you feel that way, don't get them! I love loose babydolls and stuff like that :)
A trick I heard for covertly getting into your lingerie: Say "I'm going to go have a shower." And then go, turn the water on, and get into your lingerie. Then, turn off the shower and go surprise him! Both my boyfriend and my roommate agreed that they would like that.
And have fun!!
