Lenny,
Oh..i lazy, i just took my bra size number and select according. Got difference ah? I realised that my pre-preg bra has become tighter and seems that the bust width has expanded, so by taking measurements now, would not be pre-preg size which was mentioned in the gap website which I dunno whether they have factored in some extras for the sizes or not.
For the pants, what is inseam? I dunno what is regular, ankle or long seam.
