Bought my girlfriend a raincoat

[Rain89]

The raincoat seems fine as a "rain jacket".

When will ladies wear something that keeps their knees warm?

If they wear something to their knees, it’s too big, if it’s to their waist, just right or a little short (Depends on the individual).

Oh, so like wet knees do you.

Another fetish to enjoy!!!

Well - does she have to wear much underneath?

Dress her in a bikini, let her wear that gorgeous mac (it will be reaaaaaally glossy in sunshine) and take a dip with her in the sea when it gets too hot.
The raincoat will even keep her dry in the sea, believe me
