Lass I don't know why you keep saying I don't understand the dictionary definition of the words, obviously as someone who can read I do  and it's pretty obnoxious
Here are the dictionary definitions again. I find it obnoxious that women's clothes can be seen in these terms. You have your interpretation of these words- perhaps you could let the publishers of the dictionary know they have got it wrong too.
immodest
ɪˈmɒdɪst/
adjective
lacking humility or decorousness.
"his immodest personality"
synonyms: indecorous, improper, indecent, indelicate, indiscreet, immoral; forward, bold, brazen, impudent, unblushing, unchaste, unvirtuous, shameless, loose, wanton; informalfresh, cheeky, naughty, saucy
"her clothes and manner were most immodest"
Definition of modest dress
(of a woman) dressing or behaving so as to avoid impropriety or indecency, especially to avoid attracting sexual attention. 'the modest women wear long-sleeved dresses and all but cover their faces'^
Modest is a loaded gendered word which casts a judgment on someone wearing clothes which are not modest
Yes it is. Enormous has said some things I find odd but she is correct in that one.
