Nostrils create bulbous looking tip; rhinoplasty necessary?

I look like I have a bulbous tip and my nose spreads a LOT when I smile. However the tip isnt solid its like a 'bubble' my nostrils make and can be pushed in easily. However my bridge is quite slim (my nose looks like a triangle!) Would I require rhinoplasty to correct this or would alarplasty or a 'tip' plasty correct it? Or even just suturing somehow?? Thank you for your time!
