Hi S.,
Being the mother of 4, I have had my share of toddlers who have hated getting dressed. My suggestion: Unless you need to go somewhere let her be naked. Especially since the weather is now warm. Take the control out of what has become a control issue. Let her be naked.
When you do have to go out, remember that she will want to go with you. Have the clothes ready at the door and then give her a choice of one of two outfits. Clearly state that you cannot go the the market, on a walk or the playground without clothes on. When she does agree to get dressed without a struggle then praise her simply then move on.
Trust me. It may be clothes this time but it will be something else in the future. A wise mother knows when not to push an issue and where to draw the line in the sand. And remember...it is just that, a line in the sand that is easily erased upon reflection and then can be redraw if need be.
Good luck.
