Age regression and clothing

Strangely enough there is clothing that relates to age regression and being a little although the first thing I'd say was you need not feel like wearing one one of or all these items, it's simply that which is commonly associated with it.
Like especially for those playing around of Six, they may see themselves as less 'adult baby' so not bothering with specifically Baby things but wear diapers which does have some real life parallels.
For me as a Junior/Middle, somethings such as Kigurumi, dungerees, dresses and a Tutu for dancing or parties say would figure in although we'd have some more formal things like school uniform, 'proper' shoes, plain blouses and so on.
The most important thing to remember is you are your own little or middle doing it as it makes sense to you in the headspace you are in.
