Looking for speedos my size
 

Hey, im looking for a new pair of swim briefs in Size F105-110 UK42-44 I56-58 D9-10 since i wanna go swimming again and dont know which i should get. Living in germany at the moment

A quick look on Ebay UK shows Arena, Speedo and Adidas make swim briefs in a 42" size.
None of the Asian brands go up to this size.
Speedo have a high waist while Arena have a lower hip style, you'll feel more secure in Speedos and your ass will hang out slightly in Arena, your choice.
Arena, Speedo and Adidas make classic racing swim briefs down to a 2" side, if you want a swim bikini with maybe 1" sides for a more "fashionable" cut on a beach or even a swim thong you may find it more difficult to find anything.
