I have a maxi dress - bias cut and quite fitted. It could do with being an inch longer - which I have worked out can be acheived if I lose an inch around the arse!
Thinking of a onesie - but - what are the straps like on them - in the pics they look quite thick - thicker than a bra strap iykwim. My dress has just thin straps (although if it doesn't warm up by the weekend - I will have a fur shrug on)
Should I just go for a high waisted shorts type thingy instead?
