Boys size 8 Vilebrequin swim trunks.

Bought from flagship store. Adjustable inside waistband (tie on front is inoperable, for decoration only) . In my opinion, these run small as they perfectly fit my average sized 6 year old. Consider purchasing for your even younger guy to get more use out of them as they have an adjustable waistband. See my other listings for a variety of patterns and sizing. Thanks so much for looking!
