Well I just came back (over the weekend that is) from my yearly underwear shop, so I have that info at the tip of my fingers.
I have to admit at this time that I am reading from the Hanes 6 bikinis for $8 with 2 free pairs that is sold in my area as part of the back to school.
The Hanes package says that a size 8 panty corresponds to a 14-16 inch pant size with a 43 - 45 inch hip. Size 7 is equivalent to a 12-14 inch pant size, and a 40-42 inch hip. Size 6 equals 8-10 pant size and 38-39 inch hip.
If you were into the economical brands you would know the sizes, so you might just buy one in say a size 6 and see how that feels before you go investing too much. I am in a size 12 pant and think my size is really a 7, though I have mostly 8's and they aren't falling off yet.
I think a jr. size 11 pant is not really equivalent to a misses 12 if I can remember back to my jr. days.
If I make a post, I am not asking for your opinion on my diet. My diet and my health issues are not open for your debate. I don't want to discuss them via pm, either.
If I want an opinion on something I will say, "Please tell me what you think about...."
