can't take it off

No it's not weird. I feel the same way like you. If a cute outfit can bring the best out of you then by all means wear it. But don't forget about hygiene lol!

Oh I don't think that is weird at all, we all want to look our best, and if we find something that helps us do that, of course we want to take advantage of that, it makes sense! I think we all have pieces like that, that we wear over and over again, just because we like the way they fit and look.

Some apparels are exactly suit us as if they are made for us, enhancing our physical attraction, it is not weird, because to be well dressed is to be well disciplined. Keep it up.

There is nothing like that feeling. You know you look good and it affects everything from your attitude to your productivity at work...and on and on! So how come everything we put on doesn't do that for us? Samson hit on it in his comment and it is something we may not be consciously aware of, but should be. It is dressing to your figure type first. If you are pear shaped you need to adjust the look to draw attention away from your bottom and emphasise your waist and top half of your body (that's just a start). Then, there is color and we all have certain colors that make our skin look great. Without going into all the possibilities, study that wonderful outfit and see how the color, style, fit flatter your figure. This may tell you how to shop for outfits in the future so that they call all be special.
