Any time DiVachata! My advice is to reduce the lifts to a minimum especially in a social context. I enjoy watching dancers which are "grounded", in other words they "feel" the floor or push/apply pressure into the floor if you like. If you are going to do a lift then the same push into the floor should be there but this time "through" your partner. This is why you both need to have good postures/frames and be close to each other during the lift or risk both of you ending on the floor.
But as I said above, my advice is to reduce lifts and concentrate on the quality of the dance. Especially this "grounded" feeling. Bigger ladies are usually more grounded than thin ones as they prefer to really step every step (transfer fully their weight) while more often thin ladies tend to keep their weight in the middle. Full weight transfer helps the dance a lot and this is why I don't mind at all dancing with bigger ladies. In fact, I would say that up there, on my top 3 dance experiences are 1 if not 2 ladies which were definately rounder but dancing with them was divine. One was an Italian lady called the "queen of reggaeton". Amazing! So don't worry too much about size but focus more on quality.
