Roxas honestly didn't want anyone thinking of him in a skirt. Thinking about being in a skirt was something even he really had no plan on imagining. Because it was a 'just no' kind of situation.
Jeans or some sort of pants would be good with him. Or even shorts. As long as it wasn't a skirt, he would be fine.
As Axel spoke, Roxas was just passing through the dressing room and he stopped, looked at his friend, and nodded, before being ushered to an un-occupied room.
And the whole changing and trying things on didn't take too long -- ten or so minutes at best (and he honestly refused to ask for Axel's opinion on some of the clothes because...akward).
