i started using "real" outfits pretty frequently at about 3 months? i think around 5 months a definite bedtime emerged, so we started changing into pjs at that point... before 5 months, she generally wore comfy pj-type clothes around the house and slept in whatever she was wearing during the day, but wore an outfit if we went out. so yeah, after 5 months we really got into day time clothes that look like "real" clothes. i like t-shirts and pants (either wool longies or jeans/sweatpants/leggings)... we don't really do many dresses since they are pretty impractical for a non-walking baby. of course, over the summer we mostly did just diaper and tshirt or onesie.
for me, it was partly that dd was premature and was and is quite petite. i felt a bit self-conscious about it at first, and noticed how people generally treated her a bit differently when she was dressed in pants and a shirt compared to a footed sleeper or something else very obviously "baby clothes." now we're just in the habit of wearing pjs at night and outfits during the day, even though no one would mistake her for a newborn any more!
i also don't like to dress her in things i wouldn't wear, so everything is very comfy (i hate tight waistbands or fussy outfits) and NOT pink

we wear a lot of navy, gray, green and brown.
