I love vintage inspired underwears (inside joke for my momma!). They are delicious. They are pretty and they are (surprise!) COMFORTABLE. All you crazy people who say thongs and g-strings are comfortable are lying. I know, because I too was part of this self torture. They are usually not even flattering. Blech. That being said, finding good quality and real vintage inspired lingerie and full fashion stockings can be daunting and cause me to start snagging cash from my childrens non-existant college funds.
So, being cheap, I have found good alternatives to the high priced boutiques. I like to think these are even better because these brands have been around a loong time.
Best everyday briefBali skimp skamp. Oh where to begin on the wonderfulness of these things! They are pretty, they are sheer, they are affordable, they almost come all the way up to my bra! Ah, the wonderfulness of Bali. I bought 3 pairs at Kohl's for 17 bucks on sale. They usually retail for about 9.00 a pair, but every department store that carries Bali always has a good sale.

There are no panty lines with these and you dont feel like you have a wedgie all day like you do with a thong. They are so awesome, even men buy them, too. I was looking up reviews on these before I went and bought a drawer full and about 60% of all reviews were from dudes. Seriously.
Best scandalous brief
Secrets in Lace sheer brief. These things are beautiful and come in a variety of colors and start at 9.00 a pair! I have seen sheer briefs go for as much as 40.00 and if I was crazy enough to spend that much on a pair of drawers, they better fix me breakfast, do my laundry and then tap-dance to entertain the company. SIL's briefs are prettier than most, resonably priced and Dita Von Teese has a line with SIL so you know they are the real deal.
Best bullet bra alternative
I like looking like I can poke some eyes out just as much as the next girl, but do I want to pay a zillion dollars for a brassiere I will wear once in a blue moon when I feel like blinding folks? No. Most quality real deal bullet bras will cost you, but if you just want a nice vintage looking alternative with some point, but not deadly point, Playtex is your man (or woman. whatever).
Yes, the good ol' Bra in a Box. 18 hours of solid support and guaranteed to never pinch, push, fuss, muss or go anywhere (even if someone is trying to remove it-ha!) cause this baby might as well be made of steel. Another plus, Playtex has thoughtfully made larger cup sizes with a smaller band size for us gals that nature decided to play a practical joke on. And they support your back. Functional and, well, functional. And if your husband, partner, significant other, restraining orderee is a fan of the Monkey Wards panty catalogue look like mine is, then you are in bid-nezz my friend. A+ in my book.
Best Full Fashion and regular stockings and garter belts
JC Penney, baby! They not only have the original open style girdles with garters, but they have panty girdles and stockings, too, for an affordable price. If full fashion is what you want (and who doesnt?) the back to Secrets in Lace. I know it would be nice to buy original deadstock full fashion stockings circa 1950's, but I dont feel like forking out 50 bucks for stockings and then buying gloves to put said ff stockings on with because if you get a snag then you are doomed. Besides that, if you are one of those unlucky ladies whose foot grew about 5,000 sizes during pregnancy (cough- thanks kids) then finding your size stockings in authentic deadstock is close to impossible. SIL has fantastic ff stockings for a great price. Like under 30 bucks great. Awesome. They even have the keyhole finish. Ah, secrets in lace, go ahead and take my husbands paycheck. I am sure he wont mind. too much. Ha!
