Marks and Spencers for bra fitting definitely.

I would avoid La Senza. I've been measured there twice and got a vastly different measurement on both occasions.

M&S have been pretty consistent.

Primark have some very pretty stuff, sickeningly cheap - but very little for the more er....full bosomed of us!

M&S handsdown!

Went there at the weekend, and was really pleased with the service.

So nice to have a bra that feels comfortable at last!

Another vote here for Bravissimo. I found M&S got me completely wrong - they measured me as a 40C when in fact I was a 34-36 DD (after being refit at a couple different shops following the M&S bras not fitting at all!) or something - it was a while ago so I can't remember exactly but it was very wrong...

I also found John Lewis very good when my breasts were smaller - Bravissimo I think only caters for larger busted women.

Ooo just got the Bravissimo catalogue through the door - they're having a massive sale!!

I've already spent far too much in their online sale!

Figleaves is another good website.

We don't have a Bravissimo shop here but we did have one called Bellissimo and I was fitted there and the woman got the size spot on with one look!
Now I shop online at bellissimo and it's fantastic.

Recently on GMTV Lorraine Kellys bit they had a lady from Rigby & Peller (Queens corsetierre)sp! They are supposed to be THE best anywhere but their Bras are very expensive.........This lady could just look without measuring and tell you what size you are......they are renowned for this! Obviously she told Madam Kelly her bra was far too small!
I think I might treat meself one day and pay a visit!!
Also if you gain/lose weight then your bra size changes!
