I wear a 40L and it is nearly impossible for me to find a bra that fits correctly and give me good lift.  I have to honestly say this is the first bra I have ever had that fit me correctly.  However, the materials it is made from make it so uncomfortable that I can only tolerate wearing it for a couple of hours at a time.  This item definitely has its place in my wardrobe, but it is not for everyday wear.

***Edit:  I have now been wearing this bra regularly for almost a year.  It has withstood many washes.  Due to the polyester, which I find scratchy, it has maintained it's shape and color extremely well.  The elastic and underwire construction hasn't worn significantly either.  I've gotten a bit more used to the underwire (I don't normally wear underwire) and I can now wear it all day, but it is still rather uncomfortable.  All in all, it the only bra I've found that gives me a "professional" look under my clothes.  Everything else I wear ends up looking like a leisure bra.

Upgraded from 3 to 4 stars because of durability.  I now have 5 and wear them regularly.

Edit 10/20/2016:  I'm back to buy a third generation of this bra.  I now wear a 36K.  It is still the only bra I've found with good fitment.  But, oh my!,  the new bras scratchy and difficult to break in.  They do get more comfortable with time.  I've never had a wire poke through, but all elastic fibers wear out over time.
