I haven't lost enough to get rid of all of my fat clothes, yet. I still wear them occasionally whether I feel fat or not, just because I'm out of my smaller stuff to wear, and they still fit OK enough. I usually feel kind of frumpy when I wear them.
But, yes, to answer your question, when I've put on a couple of pounds or if I'm just feeling fat, or if I'm retaining water I will choose those looser clothes over the tighter ones. I don't want to feel uncomfortable. Today is case in point. I haven't gained anything, but I can feel the water retention and I feel big. I'm wearing loss, comfy clothes today.
I hate those innocent comments from kids! They don't mean any harm, but it stings! My daughter told me she liked sitting on my lap because I'm squishy, once.
