The mid monsoon will welcome you both, so carry nice big American umbrellas. The Bangalore weather has gotten a lot hotter (due to the pollution, dust etc.), so you won’t need any thick clothing at least until late September, but be sure to ask MDG, if she’s super sensitive, to get a few air masks to get acclimatized.

Starting October (and previously, even evenings and nights August onwards), a light to medium thickness jacket or sweater will make you comfortable. If you think of driving a bike, then these, along with a head cap, will be especially useful on all mornings and evenings.

In December and January, you may need slightly better winter wear. Perhaps an extra layer.
