Non uniform wear

Although much of this blog looks though the eyes of school uniform, being a Middle in a CG/l or disciplinarian relationship this doesn't preclude everyday or play clothes as part of what you were.
Just like an actual child you do wear things outside of those so what could be more appropriate than having your caregiver putting you in cute girlish helly kitty t shirts like this graphic one as it helps you feel their own little/middle as you play in their presence.
