Live in a block of flats. I jokingly said to my neighbour opposite, after she was shocked at how much DS had grown, that if her DH was throwing any clothes out, I'd take them for DS.
She called me over today and offered me some good quality winter fleeces, jumpers and windproof jackets that were hers but are now too small for her and she's had boxed since 2019. She said I could take the lot for DS and put the more girly ones aside for DD. I've separated out the ones DS (wears adult S/16 year old) could get away with wearing, DD (10, clothes size 10 years) has already commandeered one. Two of the jackets and one of the fleeces would fit me. WIBTU to wear them and not put them aside for DD? If I do, it's highly likely she'll see me wearing them at some point.
YABU - box them up, she gave them for the DC
YANBU - It'll be a few years before they fit DD, wear them.
