Continues to be an issue for all women (it's certainly one for me!).
Ms. Angie over at YouLookFab checks out a new site that aims to help women find the perfect fitting pant...
Fitlogics Answer to Pant Sizing
I tried them out, only to find out that they don't have the Plus Size sizing up and running yet! (Even through they do give you that choice for the question, what size pants do you normally buy!). They do clearly state that it is coming and the site gives you an opportunity to sign up to be notified when it is available.
As you know this is the holy grail of the retail world...trying to come up with some way to standardize sizing for women! Personally, I agree with Ms. Angie - it's a pretty much impossible task since women's bodies are so different from one another.
She's right - for now your best bet is to find pants that fit you best in your most troublesome area and have the rest altered to fit! (But I admire Fitlogic's attempt -so I've added a link for them at the left! ;- ) )
