I recently went to try on dresses and fell in love with a fit and flare dress, however it felt extremely tight around my legs and therefore making the dress uncomfortable and it would be very hard to dance in! The sample dress I tried on was also way too small, so I know that I would definitely be ordering a couple sizes up, but will ordering up make the dress more comfortable, or are all fit and flare dresses meant to be super tight around the thighs so that it is hard to move comfortably? During alterations, can I make the dress less tight, or again are fit and flare dresses not meant to be altered to be more sheath fitting? Thanks in advance!
