Pros
Pro Sizing by bra size
Because the VS Sports Bra goes by cup and band size instead of just small, medium, large, etc, this bra can be a much better fit for women with a larger band/smaller bust or larger bust/smaller band sizes, as compared to just S/M/L, which scale cup size with band size.
Pro Front close bra
The front close makes it very easy to take on and off, instead of struggling with closing in the back or getting a tighter band, which is required for maximum support, over your head
Pro Underwire provides additional support
This makes the bra great for high impact exercises like running, boxing, HIIT, and more.
Pro Very supportive for women with cup size D and under
Pro Each cup size is a different bra that is specifically made for that size
Pro Front close bra
Front close system makes it much easier to get on and off
Cons
Con Expensive
Over $60 each without sale. Watch for the Victoria's Secret semi-annual sale in June and December to get the bras for a lower price. E-mail have discount offers, Angel Card members get additional percent off during certain times, and there are limited time events (unpredictable) for VS Sport that come in emails.
Con Front zipper is uncomfortable
Con Underwire can dig in
Especially more common for smaller band sizes, the underwire can start digging into the ribs and become very uncomfortable
Con Only available for cup sizes A - D and band sizes 30-38
Very limited range of sizes makes it much harder to find this bra in "true" bra sizes. However, will fit most those who are comfortable wearing a higher or lower band sister size
Con No color options except for black
Very basic bra color
