Not unusual for plants to become a bit droopy after repotting. Give it a bit of time. If the soil is very light and fast draining you shouldn't have trouble with that pot. But over time organic matter in the soil decomposes and the soil becomes heavier and less well draining. You need to watch for that, especially the larger the pot.

To add to Tropicbreeze, by light and fist draining it means adding solids to the soil. Things like perlite, horticultural charcoal, bark pieces, or gritty clay, lava and pumice.(bonsai substrate) This allows oxygen to still flow down to the roots after watering. Especially in a pot that is much bigger than the root mass. Though in my experience, pots with the saucer attached generally don't drain well enough and the soil ends up staying wet for too long.
