Hahahah oh Boomy, don't worry it happens to us all. Just days ago I recoiled in absolute horror of photos taken of me at the playground because I looked more turnip with legs than woman of human origin.
Your encounter reminded me of a time many years ago I went clothes shopping with a buddy and after he tried on countless sets of trousers (which were all shite in his opinion), he found a pair that he really liked and then was too embarressed to buy them because they came from the ladies section.
Clothing shopping is generally shite, don't feel alone.
