This is the most obvious sticking point when it comes to
lingerie shopping, and also the trickiest to guess - so don't.
Be sneaky, have a little rummage through her lingerie drawer
when she isn’t looking (just don't get caught red handed).
Look at more than one style, sometimes us ladies wear different
sizes - if this is the case, go for the most popular. Also check
her dress size too - handy when buying the matching knickers and
nightwear.
