[Recommendations?] Prima Donna 34F seeking department store (i.e., less expensive) options.

Hello! I wear a Prima Donna 34F Couture bra, and I love it! It fits well and is very supportive (though gets a little uncomfortable at the end of the day). However, I do not like the price. I usually only buy a bra or two a year, and I'd love to find a less expensive option that I can get at a department store, preferably Nordstrom. I've worn Chantelle with decent success (back when I weighed 20 lbs less, though), if that's an option. I tried Bratabase, but the Couture bra post doesn't list any alternatives. I should mention that I prefer "pretty" bras. I also shy away from t-shirt bras (preferring instead to go with a pretty bra and a cami on top).

This is all the measurement fit information I've been able to gather so far on myself:

1. Snug Underbust: 35 inches
2. Tight Underbust: 31.5 inches
3. Standing Bust: 43.5 inches
4. Leaning Bust: 46 inches
5. Lying Bust: 43.5 inches

Calculated bra size (using above): 34 GG/H (I wonder if I'm not measuring correctly because my Prima Donna 34F fits perfectly, I think). Projection: shallow Fullness: even (I think)

I'd love some recommendations, if anyone has any. Oh, according to Bratabase, the Coutour in my size has the following measurements:

Cm Fits ribcage: 0.0 Stretched Band: 80.0 Band Length: 69.7 Cup width: 15.1 Cup depth: 25.3 Wire length: 29.9 Cup separation: 2.3 Gore height: 7.9 Wing height: 9.7 Strap width: 2.2 Hooks: 0

Thanks in advance!
