Some advice

Hello everyone, I'm new to the lolita style, but love it. You see the thing is that I really want to wear lolita stuff, but not so OTT, more like something casual, mainly because I live in a country where is summer the whole year (not really but it's always so hot) in the mornings I go to classes and in the afternoon I have office work, a secretary. So, would you be willing to give some advice?
