Do you have something more elegant?
'Elegante' — 'e-le-GAN-te'. Stress on the third syllable. Don't shorten the 'e' at the start.
When shopping for a formal event, business meeting or dinner. Italy has a sharp distinction between casual and 'elegante' — never conflate them.
'Qualcosa di più + adjective' = something more + adjective. Dropping 'di' would be an error: NOT 'qualcosa più elegante' but 'qualcosa di più elegante'.

Classic style as opposed to trendy or casual
Italian dress codes are taken very seriously. 'Elegante' for a wedding means formal suit or dress — never jeans, even dark ones. 'Smart casual' at a restaurant still means a collared shirt and leather shoes for men.
