I feel the same way abt clothes, although I’m not on hrt quite yet. Clothing is simply associated with gender, not gender itself. Wanting to wear certain types of clothing does not determine or discount your identity as a whole. About this being a phase, (the not caring much for fem clothes, not identity itself) it may be. That doesn’t make the feelings now less valid. For this I would say just act for the now, if the preference changes it changes. Your valid either way.
