I will tell you that dress code at signatures is probably the #2 hot topic on the restaurant board, with "catering to picky eaters" being #1. Holy crap do both get my goat, especially the picky eater thing since I have one and since it always feels to me like I am being judged for not tying my child to a chair and force feeding him broccoli or starving him until he'll eat it. My personal thing, I have seen him struggle so much to try new things that are challenging textural and taste wise and literally be sobbing because he wants to please me so much and try whatever it is but he just can't make himself that I now feel like I am the champion of every picky eater in the world and can't keep my mouth shut, lol. But I digress.
People will SAY that you should dress up for signatures but honestly, like
@LBlovesM&WDW I don't really. I may try to choose a non disney tee and just a plain solid tee instead and I never wear shorts but I might wear the khaki capris I brought ANYWAY instead of the denim ones, and I think I did the flip flop thing I suggested to you (with pedicured toes lol) and just stowed them for later since they are NOT good walking shoes for someone who is overweight with high arches. But kiddo wore his space mountain shirt because he wanted to wear it while looking at it from the same view, lol
so who is gonna tell me that is not appropriate to wear at a disney restaurant? IMO anyone who is noticing what other people are wearing around them is not having a good enough time themselves. The ACTUAL rules are very loose and very common sense... nothing obscene, no swimsuits, no cutoffs (I think they mean daisy dukes, if you turn a pair of jeans into capris and roll the cuffs I think it is just fine) and no tank tops - I am pretty sure they don't mean camis for women either, they mean wifebeaters with hairy stanky arm pit hair hanging out on men. Pretty much anything remotely decent is within the rules and if you feel like dressing up any more than park wear, it is totally at your discretion. Some people LIKE to dress up and are not going to parks before and/or after and so they do and it enhances their vacation. For me it is hassle, lol. We went to MK after so we dressed ready to go

Just don't ask about it on the restaurant boards!
